RO/DI Solutions

Hello all,

OK so I just bought my first RO/DI unit second hand, but the thing runs like a champ and its practically new! I keep Apistogramma and I'm curious as to how you all treat and buffer your water so that it's the same every time. What do you do?

Depending on the fish, I will mix 50-50 or 25-75 tap to RO but I don't do anything to the RO since I'm not using it straight.
