Also, my pH is a little higher than I want. I'm using RO water, with seachem equilibrium to add minerals and electrolytes, and I'm using seachem acid buffer to try and get it down. Do you think the yeast reactor will help lower it from the CO2? Or any other suggestions. I'm guessing the RO water doesn't have much buffering capabilities but I am using equilibrium to help with that. Maybe I need more? I didn't really want to use my tap water because there's no telling whats in it.
