RO water/Tap water
I have been using RO water for over a year because of the poor water quality
here in Waco, Texas. I have been adding Kents RO Right, Dupla KH-Bilder and
Duplagan to bring my KH to about 4 or 5. I have been considering adding Waco
tap water instead to bring my KH to 4 to 6. I am not a chemist and I don't
know how much tap water to add to the RO water. Here is the water analysis
that I received from my water treatment plant.
Constituent Name Result
Total hardness as CaCO3 179 mg/l
Ph 7.5
Tot. Alka as CaCO3 154 mg/l
Bicarbonate 188 mg/l
Carbonate 232 mg/l
Nitrate (as N) 1.46 mg/l
I would appreciate any help that someone can give. I would like to know how
many gallons of tap water I should add to bring water up to a KH of 4 or 5
and a reasonable total hardness to match. I have lurked on this group for
quite awhile and have benefited by owning a beautiful planted aquarium.
