Does anyone recall the differences between diatomaceous earth made for aquarium filtration and the kinds you can pick up at a garden supply? I remember there being something negative about the "garden" variety but don't remember eactly what.
I've always used what I got at a pool supply store with no ill effects.
Bought a huge bag for really cheap.
PS Ricky- do you still have apistos? I had some of your cacs from Bailin years ago.
Yep the pool store stuff is super cheap and you can get a huge bag. It will last forever. The main thing with this stuff is absolutely under no circumstances ever breath it into your lungs. I always hold my breath every time I dump it in to get it into my H.O.T. Magnum filter.
