Hi,
I sent a response yesterday but it's not showing up on the thread. Let me try again.

First, thank you so much for the information and advice.
I have a plaster pool that always trended toward alkaline and is doing that more so since replastering last fall.

That replastering was the impetus to research the BBB method. I came away from my research with the notion that using Borax was better than baking soda because it had the benefits of raising TA, buffering/stabilizing PH, and acting as an algaecide. (It has certainly raised my TA readings.) The caveats were that it takes a lot more borax and it had to be mediated with muriatic acid. Perhaps, this use of borax was a minority opinion and I got the wrong impression but my pool performance has been stellar.

In any event, I am concerned now that I may have too much borax in the pool. Can do this cause damage? If so, what can I do? (For sure, I'll order some strips.) Thanks again, Rebecca
