I have a 75 gallon fish tank that I would like to use my weekly water changes to supply water to my two 4 gallon reservoirs. The ppm read 1600 on average at a 7.2 Ph. I have a friend who only uses fish pond water for his outdoor grows.
Question is will PhDown effect the usefulness of the fish tank water?
