Provide both mechanical and biological filtration. Simply install an airline into the unit and provide both aeration and filtration for your fish. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. The sponge traps larger waste particles mechanically cleaning the water without trapping baby fish. Product dimensions: 5.0"L x 1.8"W x 5.5"H; sponge dimensions: 2.4"D x 4.5"H. They are useful for as breeding filter or as secondary filter. Or they can be used as pre-filtration unit by fitting to an external or a top filter.

Works very well in filters

I received these 4 packs and singles. But it is better. Single order has only one suction cup. It has two. Also, this one produces more bubbles and is easier to set up than an order. You really are different.

Pros
  • Absolutely amazing!
Cons
  • -

These are great filters. I have mine GOLS certified for 10 gallon

These are great filters. I have mine in 10 gallon, 20 gallon and 55 in addition to HOB filtration. The fourth works in another tank only for "sowing". I would recommend these. The company shipped quickly and well packaged. Very happy with my order.

Cons
  • Crumpled

Ideal for betta pumps and aquarium filters

For the purposes I use them for (many betta tanks are powered by a single air pump) they are PERFECT. Using 8 of these on a large air pump is a lot cheaper than using 8 separate power filters. Betta also like that there is less turbulence in their tanks. As some other people have mentioned, they are a little larger than I thought they would be, but that's okay. large surface area for beneficial bacteria to grow.

Pros
  • Delivery was very quick
Cons
  • Not sure
