Yes, this insert is specifically designed to fit both the Fluval AC70 and AC110 power filters.
How often should the insert be replaced?
The insert should be replaced every 4 to 6 weeks, or when the water quality begins to show signs of ammonia buildup, depending on tank conditions.

Sally Davies –
Used this insert after a new tank setup with high ammonia levels. The filter quickly reduced ammonia, and my fish showed no signs of stress. Easy to install and fits perfectly in the AC70 filter.
Evan Pullman –
Helped during a sudden ammonia spike in my 55-gallon tank. The water clarity improved and fish stayed active. I plan to use it regularly in new setups.
Richard Kerr –
Great product for new aquariums. The ammonia levels dropped within a few days. Works well with the AC110 filter and doesn’t clog easily.
Dorothy Lewis –
It works, but I noticed it needs to be replaced sooner than expected in a heavily stocked tank. Still effective for short-term spikes.
