i have a penguin 200 on my 30 gallon and i was wondering if i could addd peat to this or do i need a canister filter....
Apistt_ed said:you really dont' need either... I have been hanging a small bag or stocking type bag holding Sera super Peat granules just above the flow of filters and powerheads and that's been more than enough to lower my ph. It also helps to use R/O water as it's easier to lower ph.
