Essential Biological Media — A Must-Have for Any

The AquaClear Biomax is one of those products that just works, and works incredibly well. I’m using it in my AC110, and the difference in stability and water quality

The AquaClear Biomax is one of those products that just works, and works incredibly well. I’m using it in my AC110, and the difference in stability and water quality has been noticeable. The ceramic rings have tons of surface area, which means tons of room for beneficial bacteria to thrive — exactly what you want for a strong, healthy nitrogen cycle. What I really appreciate is how clean and consistent the product is. The rings aren’t dusty, they rinse easily, and they come in a sturdy mesh bag that drops right into the filter without any hassle. Paired with the AquaClear sponge and carbon, it creates an extremely reliable 3-stage filtration system. Since adding Biomax, my tank parameters have stayed rock-solid, even with a heavy bioload. No ammonia spikes, no weird fluctuations — just stable, healthy water. This is one of the best upgrades you can make for long-term tank health. If you own an AquaClear 70 or 110, this is an absolute must-buy. Highly recommended!

Our household has long relied on Fluval products, particularly for filtration, and they continue to exceed expectations. We currently use both a large Fluval canister filter and a Fluval hang-on-back filter, and the performance of their filtration media has been consistently excellent. We have never encountered any issues with their filter media, and the quality, reliability, and effectiveness remain unmatched in our experience. For these reasons, we confidently give all Fluval filter media a 5-star rating.

Having Biomax in my aquarium is an important step for me. I have goldfish and I do not use gravel on the bottom of my tank. This product makes sure there is enough bacteria living in my filter and doing its job in keeping my tank healthy and clean! It is so easy to put these packages in and keep everything neat.

Nice Product!

Very nicely contained and easy to initially rinse. We have big fish and they eat a lot so there is always a need to balance waste to keep tank from becoming toxic. Fishes

Very nicely contained and easy to initially rinse. We have big fish and they eat a lot so there is always a need to balance waste to keep tank from becoming toxic. Fishes are happy and did well with change over to the new filtration system. They appreciate a nice clean environment.

I use this for my bare bottom axolotl tank where they produce a lot of waste. I noticed my nitrite level has gone done slowly each time I check. The filter does not effect the air flow.
