Re: Profile

I used Profile soil in a ten gallon tank using a Jim kelly style sand
over vermiculite substrate and while I got good plant growth I also had
a serious GH problem. I would reduce the hardness with changes and it
would be back up within a day! And the hardness built up during the
space between changes. Just how much did you use? I used two quarts in a
ten gallon tank. Think I used too much?
