Must-Have Accessories for New Aquarium Owners

Setting up your first aquarium is exciting, but the wide range of equipment and accessories can quickly become overwhelming. The right tools will not only keep your fish healthy but also make aquarium care easier and more enjoyable. In this guide, you will find the most important accessories every new aquarist should consider, along with practical tips for choosing and using them. MB Store provides a wide selection of aquariums and aquarium equipment to get you started on the right foot.

Essential Life‑Support Equipment

Before thinking about decoration or rare fish, you need a stable environment where aquatic life can thrive. Several devices form the basic life‑support system of any aquarium. Investing in quality here pays off with fewer problems, healthier fish, and less stress for you.

The three pillars of a healthy tank are filtration, heating, and lighting. Each plays a specific role in maintaining stable, safe conditions. MB Store offers aquariums and aquarium equipment suitable for beginners and more advanced keepers, so you can build a complete system with compatible components.

Filtration: the heart of your aquarium

A good filter cleans the water, removes debris, and hosts beneficial bacteria that break down toxic waste. Without effective filtration, ammonia and nitrite levels can quickly rise and harm your fish.

• Internal filters – Compact, easy to install inside the tank, ideal for small aquariums and beginners.
• Hang‑on‑back filters – Hang on the rim of the aquarium, offering mechanical and biological filtration while saving space inside the tank.
• Canister filters – External units with large media capacity, perfect for medium to large tanks or heavily stocked aquariums.

When choosing a filter, check its recommended aquarium size and flow rate. A useful guideline is to circulate the full tank volume at least four times per hour. For example, for a 60‑liter tank, look for a filter with a minimum of 240 liters per hour. MB Store’s assortment includes filter models in different sizes, so you can match the power to your aquarium volume.

Heaters and temperature control

Most tropical fish need a stable, warm environment. Sudden temperature changes cause stress and weaken the immune system, leading to disease. A reliable heater is therefore one of the first accessories you should buy.

• Submersible heaters – Fully placed in the water, often with an adjustable thermostat. They are the most popular choice.
• Inline heaters – Installed on the filter hose, leaving the tank interior free from visible equipment.
• Heater guards – Simple covers that prevent fish from contacting hot surfaces or breaking the glass.

A common rule is to select about 1 watt of heating power per liter of water, adjusting for room temperature and whether the tank is in a cold location. For a 100‑liter aquarium, a 100‑watt heater may be enough in a warm home, while in cooler rooms, a stronger model or two smaller units might be required for better heat distribution. Use a separate aquarium thermometer to verify that the set temperature matches the actual one.

Lighting for fish and plants

Light allows you to enjoy the colors of your fish and, if you keep live plants, supports photosynthesis and growth. It also helps fish maintain a natural day‑night rhythm. While fish do not need overly strong light, plants require appropriate intensity and spectrum.

• LED lights – Energy‑efficient, long‑lasting, and available in various color temperatures. Many modern units include dimmers and timers.
• Built‑in hood lights – Common in beginner tanks; simple to operate and sufficient for low‑light plants or fish‑only setups.
• Clip‑on or suspended fixtures – Flexible options that can be moved or upgraded as your aquarium evolves.

Plan for 8–10 hours of light per day. A timer is a simple accessory that ensures stable lighting periods, reducing stress for fish and helping to control algae. MB Store carries complete aquarium sets that include basic lighting, as well as separate fixtures for custom setups.

Tools for Water Quality and Maintenance

Clean, stable water conditions are the foundation of successful fishkeeping. Even with excellent filtration, regular maintenance is essential. Simple tools and test kits make these tasks easier and help you react quickly to problems before they become serious.

Water test kits

Testing water parameters is crucial but often neglected by beginners. Invisible substances like ammonia, nitrite, and nitrate have a huge impact on fish health. With proper test kits, you can track how your aquarium is cycling and whether it is safe for new inhabitants.

• Ammonia, nitrite, nitrate tests – Fundamental for understanding the biological cycle and preventing poisoning.
• pH and KH/GH tests – Help you adjust water hardness and acidity to match your fish species.
• Combined master test kits – Economical sets containing the most important tests in one box.

In a new aquarium, test at least twice a week. Once the tank is stable, weekly or bi‑weekly tests are often enough, with extra checks after adding new fish or changing maintenance routines. MB Store offers liquid test kits and convenient strips, making it easy to monitor water chemistry from the start.

Gravel vacuum and water change tools

Regular water changes remove waste, reduce nitrate levels, and replenish trace elements. A gravel vacuum not only siphons water but also cleans the substrate by lifting debris without removing the gravel itself.

• Manual siphon vacuums – Simple tubes with a hose; you start the flow by pumping or sucking gently.
• Python‑style systems
• Battery‑powered cleaners

During a water change, aim to replace 20–30% of the tank volume weekly or every two weeks, depending on the stocking level and filter capacity. Always match the temperature of the new water to the aquarium and treat tap water with a dechlorinator before adding it.

Algae scrapers and cleaning accessories

Algae growth on the glass is completely normal. It does not mean failure, but it does reduce visibility and can become unsightly if ignored. The right tools let you clean the glass quickly without scratching it.

• Magnetic glass cleaners – One part inside the tank and one outside the glass allow you to clean without getting your hands wet.
• Razor‑blade style scrapers – Effective on stubborn algae; use carefully on glass and never on acrylic tanks.
• Soft sponges and pads – Gentle options for regular maintenance and plastic surfaces.

Clean glass surfaces before every major water change so loosened algae can be removed with the siphon. Keep separate sponges for aquarium use and never mix them with household cleaning products, which can leave residues dangerous to fish.

Water conditioners and beneficial bacteria

Tap water often contains chlorine or chloramine, which are harmful to aquatic life. Water conditioners neutralize these substances and can also bind heavy metals. When setting up a new aquarium or after a large water change, a conditioner is practically mandatory.

• Dechlorinators – Neutralize chlorine and chloramine instantly.
• Bacterial starters
• Stress‑coat formulas – Add protective slime‑coat enhancers that support fish health during transport or after injury.

Use these products according to the manufacturer’s instructions, based on the volume of new water you are adding. MB Store offers a wide selection of conditioners and bacterial supplements to help you establish a stable, mature aquarium more quickly.

Feeding Equipment and Fish‑Care Accessories

Feeding might seem simple, but controlled, appropriate food delivery has a big effect on water quality and fish health. Overfeeding is one of the most common mistakes among beginners, leading to pollution and disease. The right accessories can prevent this and simplify daily routines, especially if you travel or have an irregular schedule.

Automatic feeders

Automatic feeders release a predefined amount of food at set times. They are ideal if you are often away from home or want consistent feeding in a community tank.

• Drum‑style feeders – A rotating drum that drops flakes or pellets when triggered.
• Multi‑portion feeders – Hold several small compartments, useful for different foods or multiple daily feedings.
• Moisture‑resistant designs – Help prevent food from clumping in humid environments.

Even with an automatic feeder, you should calibrate the portion size in advance and monitor how much food your fish actually eat. Any uneaten food should be removed, as it decomposes and impacts water parameters.

Food types and storage

A varied diet covers nutritional needs and encourages vibrant colors and natural behavior. Depending on the species you keep, you may need different food formats and compositions.

• Flakes and micro‑pellets – Suitable for most community fish and easy to portion.
• Granules and sinking pellets – Ideal for bottom‑dwellers and shy species that feed near the substrate.
• Frozen and live foods
• Vegetable‑based foods

Store dry foods in a cool, dark place and close containers tightly to protect vitamins from moisture and light. Buy amounts that you can use within a few months, rather than very large packages that may lose freshness over time.

Fish nets and handling tools

A soft, appropriately sized net allows safe transfer of fish during cleaning, quarantine, or re‑scaping. A dedicated net also reduces the risk of injury and stress.

• Fine‑mesh nets – Gentle on delicate fins and suitable for small fish.
• Larger, deep nets – Better for active or bigger species that can jump.
• Breeding traps and boxes – Provide a safe space for fry or for isolating aggressive individuals.

Always wet the net before use to reduce friction and be patient when catching fish. Avoid chasing them wildly, as this can cause panic and collisions with decorations or glass.

Medications and quarantine tanks

Even with excellent care, illness can occur. Having a few basic medications and a small quarantine or hospital tank helps you react quickly without dosing your entire main aquarium.

• General anti‑parasite treatments – Useful against common external parasites.
• Bacterial medications
• Simple quarantine tank

Use medications only when necessary and always follow dosing instructions closely. Overuse can harm beneficial bacteria and stress healthy fish. MB Store supplies both medications and small aquariums that are perfect for use as quarantine or hospital tanks.

Aquascaping and Substrate Essentials

Once life‑support and maintenance tools are in place, you can focus on creating an attractive, functional layout. Aquascaping elements such as substrate, rocks, and plants are not just decorative: they influence water chemistry, fish behavior, and even filtration efficiency.

Choosing the right substrate

The substrate is the base layer covering the bottom of the aquarium. Fish often interact with it directly when foraging, digging, or resting. Plants also depend on the substrate for root anchorage and nutrient uptake.

• Inert gravel – Suitable for most community tanks; comes in various grain sizes and colors.
• Sand
• Plant substrates – Nutrient‑rich soils designed to support demanding live plants.
• Specialist substrates

Rinse gravel or sand thoroughly before use to remove dust. For planted aquariums, combine a nutrient layer with a decorative top layer to balance plant needs and aesthetics. MB Store offers ready‑to‑use substrate blends tailored for different styles of aquascaping.

Hardscape: rocks, wood, and structures

Hardscape materials define the shape and character of your layout. They create hiding spots, territories, and vertical interest, making the tank feel more natural for your fish.

• Natural rocks – Such as slate, lava rock, and seiryu stone. Always ensure they are aquarium‑safe and do not release harmful substances.
• Driftwood and roots – Provide a natural look and subtle tannins that can benefit some species.
• Artificial decorations

Arrange hardscape before filling the tank completely with water. Ensure rocks and wood are stable and cannot collapse if fish dig beneath them. Avoid sharp edges for species with delicate fins or those that swim close to structures.

Live plants and planting tools

Live plants improve water quality by using nitrate as a nutrient, compete with algae, and form natural shelters. Many beginner‑friendly species grow well under moderate light and do not require pressurized CO₂ systems.

• Easy plants – Such as Anubias, Java fern, and various mosses that can be attached to rocks or wood.
• Stem plants – Grow fast and absorb excess nutrients, good for new tanks.
• Foreground carpets
• Planting tools – Tweezers and scissors for precise planting and pruning.

When planting, keep species with similar light and nutrient requirements together. Regular trimming prevents overgrowth that can block light and restrict swimming space. MB Store provides a selection of hardy plants, fertilizers, and tools that make planted aquariums accessible even for beginners.

Safety, Covers, and Practical Add‑Ons

A well‑equipped aquarium is also a safe aquarium—for your fish, your home, and yourself. A few additional accessories can prevent accidents, reduce evaporation, and improve daily usability.

Aquarium lids and covers

Many fish are surprisingly strong jumpers. An open tank looks elegant, but without some form of cover you risk waking up to find a favorite fish on the floor. Covers also reduce evaporation, dust, and contamination.

• Glass lids – Discreet and easy to clean; can be combined with separate lighting units.
• Plastic hoods – Often come with built‑in lighting and feeding flaps.
• Mesh covers

Measure your aquarium carefully before choosing a lid and ensure there are openings for cables, hoses, and feeding. Check that all gaps are small enough to prevent fish escapes and that condensation is directed back into the tank.

Power strips, timers, and cable management

An aquarium setup often uses several electrical devices: filter, heater, light, air pump, sometimes CO₂ systems. Organizing power connections safely is crucial.

• Surge‑protected power strips – Help protect equipment from voltage spikes.
• Timers – Automate lighting cycles and, if desired, feeding or CO₂ injection.
• Cable clips and labels – Prevent tangles and make it easy to identify each device.

Always create drip loops in cables so water running down a cord cannot reach electrical outlets. Place power strips above the floor but away from direct splashes. Taking a few minutes to arrange cables at the start will save you headaches later.

Backgrounds and viewing enhancements

An aquarium background is more than a decorative touch. It hides cables, prevents visual distractions, and makes fish feel more secure by closing off open sides.

• Printed film backgrounds – Imitate natural scenes or solid colors.
• Painted backs – Provide a clean, professional appearance.
• 3D backgrounds

Dark backgrounds often bring out fish colors more strongly, especially in brightly colored species. Apply film backgrounds carefully to avoid bubbles and ensure that they can be removed or changed if your taste evolves.

Planning Your First Setup with MB Store

With so many accessories available, it is helpful to approach your first aquarium as a complete system rather than a random collection of items. Start by deciding on tank size and the species you wish to keep, then select compatible equipment around those choices. MB Store offers aquariums and aquarium equipment in various sizes and price ranges, making coordinated planning straightforward.

Choosing the right aquarium size

New aquarists often assume that a smaller tank is easier to manage. In reality, smaller volumes are less stable: temperature and water chemistry change more quickly. A medium‑sized aquarium offers a better margin for error and more stocking options.

• Up to 40 liters – Suitable for nano setups or a single small species.
• 60–120 liters – Excellent starting range for community tanks.
• Over 120 liters

When selecting an aquarium at MB Store, consider not only the volume but also the dimensions. Longer tanks provide more swimming room than tall, narrow models and allow better layout flexibility.

Building a complete beginner bundle

To avoid missing crucial items, create a basic checklist grouped into life‑support, maintenance, and layout components.

• Life‑support: filter, heater, thermometer, light, lid or cover.
• Maintenance: test kit, water conditioner, gravel vacuum, algae scraper, bucket reserved for aquarium use.
• Layout and livestock

Many MB Store aquarium kits already include a tank, light, and filter. You can then add a heater, test kit, and chosen decorations to complete a beginner‑friendly package.

Setting up and cycling your aquarium

Resist the temptation to add fish immediately after filling the tank. The biological filtration system must mature first, a process known as cycling. This allows colonies of beneficial bacteria to develop and convert toxic ammonia to less harmful nitrate.

• Step 1 – Rinse substrate and decorations, arrange hardscape, and fill the tank with treated water.
• Step 2 – Install and start all equipment: filter, heater, and lighting.
• Step 3 – Add a source of ammonia (such as fish food) and use bacterial starters if desired.
• Step 4 – Test water regularly until ammonia and nitrite drop to zero and nitrate appears.

This process can take several weeks, but it is essential for long‑term success. By using the accessories described above and following test results, you can be confident that the aquarium is ready for its first inhabitants.

Common Beginner Mistakes and How Accessories Help Avoid Them

Certain recurring problems appear in many new aquariums. Equipped with the right accessories and knowledge, you can prevent most of them and provide a stable environment from the start.

Overfeeding and poor water quality

Excess food decomposes into ammonia and nitrate, favoring algae and stressing fish. Automatic feeders and measuring spoons help standardize portion sizes, while test kits show when water quality begins to deteriorate. A gravel vacuum removes leftover food from the substrate before it breaks down fully.

Unstable temperature and stress

A cheap, unreliable heater or a lack of thermometer can expose fish to frequent temperature swings. A quality heater matched to tank size, along with a separate thermometer, allows you to spot issues early. Heater guards add a layer of protection for both fish and equipment in crowded or busy tanks.

Neglected maintenance

Without the right tools, cleaning can feel like a chore and is easy to postpone. Having a dedicated bucket, siphon, algae scraper, and towels stored near the aquarium transforms maintenance into a predictable, short routine rather than an exhausting task.

Incorrect stocking and lack of hiding places

Choosing too many fish, or species with incompatible needs, often leads to aggression and stress. While accessories cannot change fish behavior, layouts with caves, plants, and visual barriers can reduce conflict and provide retreat areas. Hardscape and live plants are therefore functional tools, not just decorative additions.

By understanding these common pitfalls and using accessories intelligently, you give your aquarium the best chance to thrive. MB Store’s range of equipment allows you to select reliable, compatible products for every stage of your fishkeeping journey.

Frequently Asked Questions

How often should I change water in a new aquarium?
In a new aquarium, plan weekly water changes of about 20–30% of the total volume. Use a gravel vacuum to remove debris from the substrate and always treat fresh tap water with a conditioner. Test ammonia, nitrite, and nitrate regularly; if levels rise, slightly increase the frequency of water changes.

Do I really need a heater if my room is warm?
Even in a warm room, temperatures fluctuate between day and night or with seasonal changes. Most tropical fish need a stable temperature range, usually around 24–26°C. A heater with a thermostat keeps water conditions constant, reducing stress and disease risk for your fish over the long term.

Can I run an aquarium without a filter?
Very experienced aquarists sometimes keep heavily planted, lightly stocked tanks with minimal filtration, but this is not recommended for beginners. A suitable filter provides mechanical and biological filtration, keeping water clear and detoxifying waste. For new aquarium owners, a filter is considered essential equipment.

When can I add fish after setting up the tank?
You should wait until the aquarium has completed its nitrogen cycle. This usually takes 3–6 weeks, depending on temperature, bacterial starters, and maintenance. Use test kits to monitor ammonia and nitrite; only when both reach zero and nitrate appears steadily is the tank ready for its first fish.

What size aquarium is best for a beginner?
A tank between 60 and 120 liters is ideal for most beginners. It provides enough water volume to keep conditions stable, yet remains easy to maintain and place in a typical home. Smaller tanks are more sensitive to errors, while very large aquariums require more powerful equipment and higher initial investment.
