what the heck is it.

a pump that draws water through a sponge

Air is pumped down in the tube and when it comes back up it pulls water through the sponge. They are great biological filters.

can also be used with a powerhead, heck i've attached it to my hob filter intakes

They are very underrated

Extremely good to have on hand, especially if you breed fish. This filter when used with an air pump avoides the chance of sucking up fry through an impeller.

They're worth twice their weight in gold.

Also an inexpensive way to complete your filtration if ya happened to buy somethin crappy like whisper. I use one and a cheap HOB in my quarantine tank, with two extra sponges in my 75's wet/dry incase I need to medicate/sterilize the quarantine tank.
