So anyways, I was searching around for a small (and I mean REALLY small) filter for my OceanFree tank and I came across this filter that is avaiable at Petco for only $7.64 USD. I chose this over the Eheim Aquaball 1212 because the aquaball was way too big for an OceanFree tank and the price was a bit overboard. Here are the specs:
Underwater filter for use in tanks up to three gallons.
* Compact design.
* Venturi with valve for added aeration.
* Adjustable output diverter.
* Adjustable flow control.
* Easy to set up and use.
* Easy to maintain.
* Improves water quality.
