DIY Sponge filter
I am wanting to make my own small sponge filters for my 10G planted tanks and in preparation for a CRS breeding tank.
I have chosen to use PVC pipe as my main tube and then your basic tubing found at Petsmart for the air to pass through.
The problem I am running into is finding foam. I've heard Open Cell Foam works well, but I really can't find any cheap. Does a sheet or portion of this foam exist under $40? I don't need to make a ton of filters, just a good handful, but I don't want to spend so much on just the foam.
I have gone to Hobby Lobby, Michael's, Roberts, Lowe's and Home Depot. Only Home Depot and Lowe's had a type of sponge in the paint/flooring section that would work, I just didn't check to see if was treated with an anti-bacterial ingredient, or whatever it's called. The other stores only had Styrofoam stuff.
Do any of you have some alternative suggestions or ideas for me that is cost effective?
