AquaClear 50 Foam Filter Inserts are replacement filter media for the AquaClear 50 Power Filter. The AquaClear 50 Foam Filter Insert is a mechanical filter media that effectively removes particles and debris from aquarium water. It also prevents particulate waste from prematurely clogging other media in the filter. Primarily a mechanical filtration media, it also provides powerful biological filtration as friendly bacteria eventually grow inside its pore structure. Exclusively designed for the AquaClear 50 Power Filter, the Foam Inserts are safe for fresh and saltwater aquariums. AquaClear creates a wide variety of products for freshwater tanks such as fish tank accessories, fish tank decorations, and aquarium filter media that is perfect for large and small fish tanks.

Good quality foam replacement filters and great price
Effective foam filters to use in a 3 stage filter system. Helps maintain water quality and clarity. No Assembly required. Longevity is better than marketed. I’m able to reuse these foam sponge filters by rinsing them in tank water until all the crud is rinsed out (DO NOT rinse in tap water or all the beneficial bacteria will be killed) These sponges can also be cut down to fit smaller off brand filter systems, and at end of life span they are good for a quick tank cleaning to remove algae from glass,etc.

Buy this, not the blue ones, for your AquaClear filter
The Fluval people are replacing this product with blue sponges made of a different polymer and with different cell sizes compared to this product. Those blue ones clog up in a fraction of the time that these yellow ones last, and when you take them out to clean them, only about the bottom 1/4â of the filter is used. These original yellow filters are matched better to the AquaClear pump strength and flow rate, so the entire filter gets used before it starts acting âclogged.â In my setup the longevity difference is about a factor of 5. If you have an AquaClear filter setup, buy these.
