That test is out of the tap correct? Well your PH is fine for Discus , especially if you do a planted tank and use a C02 system or if you get your hands on Chemi-Pure over there then I don't see a reason to use RO unless your planning one of those BUBB (Butt Ugly Bare Bottom) and or you plan on breeding them.


and no I hadn't had a drink at the time
