Sponge Aquarium Filters
A sponge filter is a simple device for use in both fry tanks and hospital tanks. In fry tanks the sponge offers a banquet of micro-organisms for the young fish to eat. Additionally they also have no dangerous moving parts or places where fry may trap themselves. In hospital tanks the sponge will not remove medications as charcoal based filter systems can.
The sponge's large surface area is ideal as a sight for biological filtration to take place. Beneficial micro-organisms will soon colonise the sponge. The sponge also makes it an effective mechanical filter for small particles.
The essential components of a sponge filter are an air uplift and sponge media. A suction cup mounted heater holder clamp may prove useful for keeping the filter submerged for some models.

KIS Sponge Filter ReviewWith the air uplift included this product measures 21.5cm in height. The sponge base is 4cm in height and the longest edge to the triangle shape is 17cm.
I think this is a good sponge filter model because of it's dense sponge. It is fine enough to mechanically filter quite small particles from the water. However it is light in weight and will benefit from being secured in place.
The KIS sponge filter typically sells for less than $10 making it good value.
