Again like I asked the OP what are you trying to do with RO
water? Go to using all RO
in your tank or cutting RO
with your tap water? There is a big difference in the two. You have to be consistent with it's use or you can cause your gh
, and ph to jump around which is not good for the fish. Is there a reason you need to use RO
? Good advice can't be given until we know exactly why you want to use it so you can be given the correct information on how to use it for what your wanting to achieve.
