These do the job well. They also don't release all the gunk back into your tank when you take them out to clean them, unlike most pre filter sponges. I also found they fit the intakes of the Aquaclear 70's and 110's perfectly.

A must-have for a clear tank

Our tank was looking kinda cloudy, so we got this bio-form to help, and boy did it! No real instructions come in the box, just a photo of where you need to place

Our tank was looking kinda cloudy, so we got this bio-form to help, and boy did it! No real instructions come in the box, just a photo of where you need to place it. Installation was easy, and we're enjoying the clear water benefits. Highly recommend if you tank needs a little extra help to keep it looking clear between water changes.
