Biological Sponge Filters are a great addition to any tank.  Air pump not included.

SKU: SPONGE Category:


Biological Sponge Filters are a great addition to any tank. We use sponge filters in all of our tanks under 100 gallons as the only filtration; plus we use them in our larger tanks instead of using air stones. Any time we need a sponge filter all we have to do is pull one out of a tank and instant cycle; and if the main filtration should fail the sponges help to avoid the tank crashing.

Size Options:

Up to 10 gallon – perfect for breeding tanks, bettas and other smaller fish that do best in a low current.

Up to 25 gallon – make excellent additions to a breeding tank

Up to 50 gallon – great economical filter

Up to 75 gallon – features a wider and taller lift tube to increase the movement of water through the filter as well as creating current in the tank itself

Up to 130 gallon – this filter is a beast. We use one in our 55 gallon rearing tanks when overcrowded and in our 125 gallon for added bacterial colonization.
