That's interesting. I wouldn't have guessed though that pH of 7.0 was enough to significantly dissolve enough aragonite to be meaningful. It would be interesting to test Ca and Alk, pre- and post- canister to see the difference. Too bad I chucked out the last bit of reactor media I had, I would have loved to try it - although I don't have a spare filter canister I could have used anyhow. Soooo ... anyone else want to give it a try and post the Ca and Alk numbers?
