I really like using the Fluval Ammonia Remover in my AC20 filter. It fits perfectly and gives me peace of mind knowing it’s helping keep harmful ammonia levels down, especially in my smaller 5‑gallon tank where water quality can change quickly. It’s simple to pop in and swapping it out every 4 weeks keeps things running smoothly. I’ve noticed my fish seem more comfortable and the water stays clear and fresh. Maintenance is easy, and I don’t have to worry about complicated steps — just replace and go. For anyone using the AC20, this insert makes tank care less stressful and helps create a healthier environment for your fish.

I'm using this in a Fluval AC 20 on a 20 gallon long tank that I am setting up for my Sakura orange cherry shrimp. The packet is easy to use and conveniently fits right in to the chamber of the filter. The water flows right through and it seems like it will improve water quality.
