dose the driftwood do the same thing a peat. Also dose peat really change the water brown. I dont know what to do thanks for the link though but i dont know if i want my ph to go down to 4-5 i want it to go down but not to much because the snail needs 7.5
Iamntbatman is correct you do not need to lower the pH. Just for future reference, driftwoods also leach tannic acids and tannins do make your water turn brown but this does not harm the fish.
