New Scaling problem.


Apr 22, 2018
I have a saltwater pool that about two months ago started to accumulate flakes at bottom. I vacuumed it all up and then cleaned both the SWG and the filter but it didn’t solve the problem. I then replaced half the water. I have a lot of scaling now and I have not had for a couple of years. I know the key is balanced PH and TA. Should I lower my PH below 7.5? Here are my numbers, any help is appreciated.

Pebble Tec Saltwater 14,500 gallons
PH: 7.5
TA: 80
CH: 425
CYA: 60

In Poolmath you should track CSI. Keep it between 0 and -0.3. The Poolmath logs you are sharing just show chemical additions. Recording your water chemistry test results really will help you over time and us when you ask chemistry questions.
