Ok so I just want to make sure that using RO/DI filtered water is ok for my fishtank. I just recently moved and the place im living now has on so I can use it if I wanted to. I first filled the tank with regular tap water and now while doing water changes am refilling it with RO/DI filtered water. It is a fairly heavily planted tank with CO2 injection with live fish. It is also fertilized regularly with micro/macro nutrients. So is it ok to use RO/DI filtered water and will this cause PH shifts or anything else that I have to worry about? Thankyou!
