CAF-10 Internal Sponge Filter
The CAF-10 is a simple, classic and economical sponge filter for beginner and advanced aquarists alike. The specially developed foam materials of each CAF sponge filter support the colonization of bacteria, allowing for mechanical and biological filtration. The process breaks down harmful ammonia and nitrite, resulting in a cleaner living environment for your fish.
The CAF-10 is weighted and uses an airlift system for superior filtration and silent operation. It can be used as a stand-alone filter, as a breeding filter, or as a secondary filter. The filter fits most external or top filters and can also be used as a pre-filtration unit.

I’ve used the CAF-10 in my 20-gallon tank for three months now. The water clarity has improved significantly. It’s quiet and doesn’t disturb the fish. I use it as a secondary filter during breeding season and the fry thrive in the clean water.

The sponge filter works well as a pre-filtration unit. It’s easy to clean and maintains good water quality. I noticed a drop in ammonia levels after setting it up. A solid choice for both new and experienced hobbyists.

I installed the CAF-10 as a breeding filter for my bettas. The water flow is gentle and the filter has helped reduce nitrite levels. It fits perfectly in my top filter setup and has been reliable since day one.
