the most important thing is to know whats in your original water source and what you are concentrating.

So if you are using ro water for your fw tanks, what supplements are you adding to make the chem correct for fw, ie trace elements, ph? If this is the case what benefits are their using ro vs conditioned tap water? It could be more work using ro vs conditioned tap water?

My tank has tetras, corys, otos, clown loaches & of course a bunch of plants. Right now all i do is use prime & tap, let it sit for day before using and add a capful of flourish excel.
