When I put the aforementioned prepared water (with a conductivity of about 17 microsiemens and a PH of 4.1) in the almost empty 10 gallon, it subsequently rose to 23 microsiemens and 6 ph! This makes no sense…the tank has no substrate nor nothing else that would obviously cause such a spectacular rise in either TDS or PH. Any suggestions on what is going wrong? (PS…this tank is bare bottom and its only decor is its leaves, sticks, and plants)
