Fluval AC Series Filter Insert Bags

The Fluval AquaClear Filter Insert Bag is the reusable nylon mesh media bag made for AquaClear (AC) power filters. Fill it with loose media, activated carbon, ammonia remover, bio rings, Purigen, or peat, and it keeps everything contained and easy to rinse, swap, or lift out at cleaning time. Each size is cut to fit a specific AquaClear model so it sits neatly in the media basket. Sold by filter size.

Match the bag to your filter below, then fill it from our Filter Media & Cartridges collection.
