About 15 years ago, when I had about a dozen aquariums running, my LFS sold 1/2 inch thick foam pads to lie on top of the under gravel filter with the gravel spread on top of it. It seemed to do a most excellent job. Kind of a combination "under gravel/sponge" filter.
The problem is, that now that I'm beginning to set up my aquariums again, I can't find an LFS that sells these 'sponge pads'. I know it wasn't special 'fish foam', but some ordinary foam that I should be able to find at K-Mart or Wal Mart.
Is most any type of foam 'fish safe'? Is there any type of foam that I should avoid for this purpose?
I just don't want to accidently poison my fish with some kind of chemical or something like it leaching into the water.
Has anyone else used this method of using a foam pad with an under gravel filter?
