Hi Surefoot;

One of my basic rules is, "If it isn't broken, don't fix it!". The numbers matter less than the results -- you swim in a pool, not in a bunch of numbers.

You could tear up a heater with those numbers, but it sounds like you don't have one -- so that's not an issue.

So . . . I'm not sure I'd recommend changing anything, other than the switch to bleach you are already planning. If you drop the bromine now, you'll have to switch to running VERY high levels of chlorine. Given your other numbers, you could end up with complications that would spoil your summer.

Instead, why don't you run just like you have been, but switch to bleach as your chlorine source.

It wouldn't hurt to get some muriatic acid, and gradually -- no rush -- lower your pH.

But I would not recommend any big changes, until this fall. Then look at it again. If your costs and chemical consumption are out of line, we can look at switching. Otherwise, "if it isn't broke, don't fix it!".
