My well water tests at a pH of 5.6 and total dissolved solids of 40. I have a downflow/backwashing 2.5 cu ft neutralizer tank filled only with calcite. When drawing a steady flow (like a shower) at 2.5 gpm or higher, the pH of the treated water levels out at around 6.5 or 6.6. I'm using an aquarium pH test kit, so I don't know how accurate the readings are. With copper plumbing, however, I'd like to get the pH closer to 7.
I've heard that using a mixture of calcite and Corosex in the neutralizer tank would raise the pH. But I've also heard that Corosex can overcorrect pH, which can create new problems. Also, if Corosex dissolves faster than calcite, it seems like it would be challenging to keep the neutralizer filled with the proper mixture.
I've been thinking that another option might be to inject soda ash before the calcite-only neutralizer. The neutralizer would then serve primarily as a sediment filter. I don't if there are side-effects to this option.
I know there are trade-offs with any solution. Can anyone share thoughts on which of these you'd recommend? Thanks.
