Soilmaster Select pH drop
I recently converted my 20H to a planted tank. I put in about 2 cups of peat moss and a small container of laterite, (I learned this from the forum, a sticky maybe) as substrate conditioners, then covered both with about 3 plus inches of charcoal colored SMS Pro.
Using Flourish Excel for CO2, which doesnt affect pH, I've noticed a significant drop in pH, from about 7.0 to 6.0.
I was under the impression the peat moss buried in the substrate would not affect the pH as would peat put in a filter for that exact reason, to lower the pH.
I'm thinking I should add carbonate or bicarbonate to up the alkalinity and pH a little.
Any one else run into this? I'm thinking now I shouldn't have added the peat.
