Introducing RODI water

[dmolavi]

I know I can't just dump all my existing water and replace it with RODI water, but what is the "best" method for switching over to RODI? Is it in small increments (ie, to do a 30-40% WC each week, adding 10% RODI to the tap water that I add), or just go all-in and start using the RODI water for the complete water change?

Why are you switching? In freshwater its not needed. But if you.must know I'd just start replacing 10-20% a day till you hit 110% changed out.

And don't forget that you need to add minerals back into RO/DI water. The stuff is not healthy and if you don't the outcome won't be good for your fish or plants.
