I am having trouble keeping my PH in check. I find it very difficult to read the color chart and match my PH. It seems to me that it is always on the high side. It doesn't match an exact color but it may be off the chart. I keep adding Muratic acid. I will be honest that it has been spuratic because of my travel schedule.

I have a 15000 gallon gunite/plaster pool. I just added a pint and a half and will evaluate again tomorrow. My current numbers are.

SWG pool

FC 2.0
CC 0.0
ALK 95
CAL 300
CYA 40
PH ???? Maybe 7.8 but difficult to read...

Is there an easier test to measure PH? Perhaps one that doesn't use color matching? BTW, I am using Ben's new kit.

Thanks! I'm looking forward to everyones great info.
