FC/CC: 3.0 pH: 8.2 TA: 80 CH:800-900 CYA:60 Borates: 50, using the TFT Kit and Lamotte test strips
Disclaimer: This post might be a bit premature, as I just added the Borates (using Mule Team and the method from this site) about 30 hours ago. I haven't adjusted the pH since I think it told me not too.
I am here seeking the pool monks' advice on how to minimize pH rise and manage CH in my hard water pool. This post was prompted by reading a couple of off-hand comments about lowering TA to 50 to balance a higher CH and prevent pH rise.
1. First, my CH is currently at 800-900. The water going in the pool is about 300ppm in overall hardness, which based on the pool school page, I would guess to be about 200ppm CH in the replacement water. I can test this if its an issue.
2. My water's pH wants to live at 8.2 and will do everything in its power to get back to that number in day or less. Preventing aeration, and so far borates, don't seem to have slowed it down a bit. This is not a new phenomena, I totally replaced the water late last summer to use the BBB method.
Any advice on how to proceed would be greatly appreciate.
Thanks so much,
