pH was 7.2 this morning, still 7.2 this evening... this is following water getting fairly low due to heat, extended backwash, and leaky multiport. How long do I let it stay there, and should I be concerned at all? I unfortunately have .5 copper in the pool, so I don't want pH to drift too high.

TA is running around 110, where should it be, and how high do I let it go before I worry?

I would add a little Borax because I'd like to get the borates in there, but it looks like lowering alkalinity is no fun, especially since I have no jets that point toward the surface, waterfallls, etc.
