I've stopped mixing equilibrium/alkaline base/acid base to get the ph where I want it with RO water and just started mixing in tap. 8.3 out of the faucet. I keep the RO in a bunch of gallon jugs and started keeping 2 gallons of tap water in jugs as well. I am adding either prime or stress coat to the tap to dechlorinate. I am wondering if I do this ahead of time a day or 2 if I can use just enough to treat the gallon and not the entire planned tank. Question is how long does it take for the prime to work?
