Is there any reason I need to keep my total all between 125-150? This is higher than what my caldera manual tells me it needs to be. Caldera says keep it at a minimum of 40. The people at ye olde spa store keep telling me 125-150. I am constantly having to add dry acid to keep my ph down when the alk is that high. The alk drops anyways after adding acid and then they want me to add alk increaser. It would make more sense to me to keep total alk lower and avoid having to add so many chemicals all together. Fwiw I'm using the spa frog system. I know it's more expensive than chlorine or straight bromine but so far it is mighty convenient and easy. Any input?
