RO in Freshwater Tank

[toyota44]

Is it O.K. to use RO H20 as replacement H20 after a water change in a freshwater tank? Do I have to add anything to it to buffer the pH etc...?

Thanks in Advance!

R.O. water has a low PH.If I remember right the PH is around 6.It also has to do w/kind of fish (freshwater).If you can tell me what kind of fish I can help you further.

YES! There are not enough minerals or buffering compounds in RO or RO/DI water. You need to add a mineral supplement. Many manufacturers (Kent Marine, Tropic Marin, Seachem, etc.) make this.

For fresh water or aquatic plant aquarium, there is no need for RO water. Just use tap water and add in antichorrine will do. There is enough minerals inside and should be save (we use it in daily use... should be save) and doesn't have much side effect. No need the touble for getting RO water or add in minerals. :>
