San Diego Water
Can anybody tell me the water parameters of San Diego? Iv'e asked the LFS of San Diego and they all say its extremly hard.
THe reason I ask is because I am using R/O water and am having a problem with the KH of my tank (a little low about 2.5). Im also very low on nitrates.
I am guessing the solution would be to cut the R/O water with some tap? Then treat with prime.
