Two kinds I have never had a problem with. Both are open-cell and neither 
seem to have any chemical bad stuff. One is regular (not automotive or 
boat) upholstery foam. The other is the cheapy, no-brand-name scrubber 
sponges from the dollar stores.

Fancy, brand-name scrubbers from the grocery store always seem to have 
those anti-fungal, anti-bacterial additives that cause trouble. I really 
like "Scotch-Brite" scrubbers for doing the dishes. They never seem to get 
smelly. I do *not* use them for cleaning tanks or in filters, tho.

PS. Open-cell foam is easy to identify. Just blow through it. If it will 
pass air it is the real thing. If you cannot blow through it, it is 
closed-cell foam and utterly worthless for most aquaria uses.
