Ph of 8.0. Do I really need to adjust?

[PoolUmp]

So, I've been reading up on effects of Ph, and am wondering if I really need to adjust my Ph? It's alway run near the high end of the spectrum. It looks to me to be between 7.8-8.0. All other values are great...

Plug your numbers into poolmath and let it calculate the CSI. If your water is real warm, you could really easily start forming scale.
