pH/heavy metals (was) Re: [GSAS-Member] Free fish food, or trade

I suppose the bottom line is whether I was able to raise the pH (and
increase the hardness) of the water in my Endler's tank. I use NovAqua
when I do water changes...and I used crushed coral, cuttlebones and an
occasional pinch of Epsom salts (when I remembered) and was able to
accomplish my goals (shrug). I raised the pH despite my use of a water
conditioner formulated to remove heavy metals (shrug). I wasn't using
dolomite, but I WAS adding minerals.
