We are just starting our third year with TFP and so far it has worked wonderfully. I want it to continue to work wonderfully, hence, I need clarification on the PH/TA relationship. For some reason, I have a big mental door shut on this one and am having a hard time coming to terms with what I need to do, what to use and in what order.
Here are my numbers from 5:30pm:
CYA 40 (I finished squeezing the dry CYA out of a sock yesterday and watched it float away into the H2O
Water temp 74
I understand I need to put in enough chlorine for shock as I have something chewing/attempting to grow in there.
Here is what the pool calculator tells me to do with the TA and PH (I love the calc btw)
(My PH is currently at 7.2)
It says to add either washing soda or borax if I want to get my PH to 7.5
*Note: pH calculations depend on TA and Borate. Results are approximate and can be off significantly for large pH changes. Changing your pH will also change your TA.
TA(currently at 130...up from yesterday's rdg of 120)
Goal: 70 to 90
*To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH.
Note: Adding baking soda will also raise your pH.
*directly from the calculator.
Please give me direction with this. The pool has been filtering for about 3 hours and the return is allowing the water to break the surface of the water in the pool.
The water is crystal clear and sparkling!!! Another victim of sparklypoolitis
Thanks for any info you can give me.
