I love these small filters!
January 27, 2014
I have 3 betta tanks and 2 of them have the CAF-10 sponge filters. The filters are great for smaller tanks, they don't take up much room, and they work great! You use them with a air pump, add a air control valve, and perfect for a betta! mine I use them in are 2.6 tanks.
Pros:Great for small betta tanks. Doesn't take up a lot of space, looks good, and works great.
