I am remineralizing reverse osmosis (RO) water (pH=7, TDS =0) by adding Seachem Equilibrium and it is spiking the pH. It is definitely not supposed to do that. Seachem says it shouldn't and other people say it doesn't effect their pH. So I figured it was a weird mistake and I started over. I tested the RO water with my pH meter and it said 7, then I added Equilibrium and I watched the pH rise from 7 to 8.3. Then I thought maybe my pH meter is off so I used my API test kit but the API kit confirmed the pH is indeed 8.3 Has this happened to anyone else? Could I have received a bad batch of Equilibrium?
