Welcome to this aquarium equipment guide! Whether you’re setting up a new tank or upgrading your current setup, choosing the right filter is crucial for the health and longevity of your aquatic environment. In this guide, we’ll dive into three popular types of aquarium filters: Hang-On-Back (HOB) filters, Canister filters, and Sump filters. Each type offers unique advantages and considerations to help you make an informed decision.
Hang-On-Back (HOB) Filters
Summary: HOB filters are impeller-powered devices that draw water from the aquarium through a siphoning tube, pass it through various filter media, and return it. They are common and suitable for larger tanks but may cause excessive water flow in smaller setups. These filters are often chosen for their ease of use and variety of filter media options. Maintenance is straightforward as they sit outside the tank, reducing disruption to aquarium inhabitants. However, their compact design limits the amount of filter media compared to canister filters, and they can be noisy due to vibrations.
Pros:
- Variety of filter media options.
- Easy maintenance without disturbing tank inhabitants.
- Suitable for larger tanks.
Cons:
- Limited filter media capacity compared to canister filters.
- Can create excessive flow rates, which may not be suitable for smaller tanks.
- Potential for noise due to vibrations.
Recommendations
For HOB filters, a reliable choice is the Aqueon QuietFlow Series. These filters are known for their extremely easy setup, effective filtration and quiet operation, making them ideal for beginners and experienced aquarists alike.
Canister Filters
Summary: Canister filters use external canisters filled with filter media. Water enters from the bottom, passes through the media, and returns to the tank via a pump at the top. They provide high filter capacity, support in-line equipment installation, and can be disconnected for cleaning. These filters are favored for their ability to hold large amounts of filter media, allowing for effective mechanical, chemical, and biological filtration. They are ideal for larger tanks and those requiring more thorough filtration, but they come at a higher cost and require periodic cleaning of the intake and return tubes to maintain optimal performance. For example, a new FX6 Fluval canister filter can cost $350 or more in many cases. Properly installed canister filters are efficient and provide flexibility in equipment setup, such as adding inline heaters or CO2 diffusers.
Pros:
- High capacity for filter media.
- Supports in-line installation of other equipment.
- Minimal disturbance to aquarium during maintenance.
Cons:
- Higher cost and complexity compared to HOB filters.
- Cleaning the intake and return tubes can be challenging.
- Risk of leaks if not properly maintained.
Recommendations
When it comes to canister filters, consider options like the Cascade Canister Filters or the Fluval FX Series. These filters are well-regarded for their robust filtration capabilities, large media capacity, and ease of maintenance, though they come with a higher initial investment.
Sump Filters
Summary: A sump is an additional tank below the main aquarium used for mechanical equipment like protein skimmers and heaters. It increases water volume, stabilizes pH and salinity, and can include a refugium for nutrient filtration. Sumps are primarily found in reef and marine aquariums where water quality and stability are critical. They offer significant benefits by enhancing biological filtration and providing additional water volume to dilute pollutants. Sumps also facilitate the installation of equipment outside the main tank, reducing clutter and improving overall tank aesthetics. However, setting up a sump requires careful planning and installation to ensure proper water flow and prevent leaks. Once established, sump systems enhance oxygenation and gas exchange, contributing to a healthier aquarium environment.
Pros:
- Increases water volume and stability.
- Mitigates nutrient buildup and stabilizes water parameters.
- Improves oxygenation and gas exchange for fish health.
Cons:
- Requires additional space below the main tank.
- Initial setup can be complex and may require professional assistance.
- Risk of leaks if not properly installed and maintained.
Recommendations
For sumps, you have the option to either build a DIY sump tailored to your specific needs or purchase a pre-made sump system like those offered by Synergy Reef Systems. These systems are designed to maximize water volume, enhance filtration efficiency, and can be customized with additional equipment like protein skimmers and refugiums.
Tips
Choosing the right filter depends on your tank size, the type of fish and plants you have, and your maintenance preferences. Remember, you can combine and double up on filtration, but there’s such a thing as overkill; after a certain point, adding more filtration can be redundant. Research and consider your specific needs to ensure a healthy and thriving aquarium environment.
Conclusion
Each type of aquarium filter offers distinct advantages and considerations. Whether you opt for the simplicity of a HOB filter, the efficiency of a canister filter, or the comprehensive setup of a sump, understanding these options will help you create a balanced and sustainable aquatic ecosystem.
Remember, the right choice of filter can make all the difference in maintaining a healthy aquatic environment.
Happy fishkeeping!
