Well, I wen to Home Depot last night, as some of you suggested, to get some Canadian Peat Moss. The only thing I found is a big bag of Canadian Peat Moss for ~$9.0, but it has Miracle Grow chemical added in. I don't think this will work for discus fish. So I didn't buy it. Where else can I buy Peat Moss that will work for fish ?
I have a 35 gallon trash can to age water. The aged water is still 8.2 ph. How much peat moss should I use to lower the pH to 7.0 ?
