Finding the Best Filter for Your Cichlid Tank
Things to Consider When Choosing a Filter for Your 125-Gallon Cichlid Tank
- Available Space – The space you have available doesn’t just pertain to the available space within your tank. You need to consider your tank space, as well as the physical space you have for a filter outside of your tank. Canister filters need to sit below the level of the tank, so you will need to be able to put the filter underneath or next to the stand your tank sits on. Even smaller canister filters can be quite bulky, so take your available space into account. Also, consider things like telescoping intakes and spray bars since these things can have an impact on the available space within your tank.
- Tank Stocking – The size of your tank doesn’t mean much if the tank is overstocked. If you were to buy a filter for a 150-gallon tank to use in your 125-gallon tank, it might be suitable for an appropriately stocked tank. However, if your tank is overstocked with large, messy livestock, then there’s a good chance you’d need a more powerful filter. The type, number, and size of fish and invertebrates in your tank can have a major impact on the filtration your tank needs.
- Water Current Needs – While Cichlids are generally hardy and adaptive fish, their tank mates may not be. Some fish and invertebrates require weaker water currents and may be overwhelmed by strong currents. Delicate plants may also need weaker water currents, while some fish and plants can adapt to any current. Consider the specific needs of all of the plants and animals in your tank and choose a filter with an adjustable flow if needed.
- Setup and Maintenance – Canister filters are often a great option because of their low level of routine cleaning and maintenance. That doesn’t mean that you don’t want things to go smoothly when cleaning and maintenance time comes, and initial filter setup can be a real burden if you aren’t familiar with the setup of canister filters. Choosing a filter that will allow you more accessible cleaning, maintenance, and setup can save you time and stress, and they may also save your floors from leaks and spills.
- Over-Filtration of Cichlid Tanks – While you might look at filtration for a 200-gallon or 400-gallon tank and think that it’s way too much for your 125-gallon tank, there are some benefits to over-filtration of Cichlid tanks. This is especially true with large fish and overstocked tanks. It’s also true if you are feeding your Cichlids large quantities of food frequently, which may be done to support growth and development, but can lead to poor water quality without adequate filtration. Check out this video explaining why some Cichlid tanks can benefit from over-filtration.
Conclusion
To pick the perfect filter for your 125-gallon Cichlid tank, use these reviews to start your research. The best overall option is the Eheim Pro 4+ 600 Canister Filter, which is a powerful filter that helps reduce cleaning and maintenance, thanks to its “Xtender” button.
The most budget-friendly pick is the SunSun HW304-B UV Sterilizer Canister Filter, which provides UV light to help keep algae and parasites under control in your tank. The premium pick is the smart and highly functional Eheim 2180 Pro 3 Thermofilter, which functions as a filter and a smart heater, but that does retail for a very high price.
