Aquarium Advice Freak
I'd like to get a couple of sponges for the ph on my MaxiJet 900. I've done some looking around, and the cost for these sponges seems outrageous, like $6 for a pair. Not that I can't afford a measly $6, but they are just sponges, aren't they? And then add $5-6 for s/h (I can't find these things at lfs). Anyone us any off-the-shelf sponge material from hardware stores or whatever successfully?
I looked at some sponges at a local Wal-mart, and they were clearly marked "Not for aquarium use" or something like that - perhaps because some of them contain chemical compounds to reduce the growth of germs.
