Preparation for SWG install

[Renro]

Greetings. I’ve read some, if not all the pool school information and just wanted confirmation on raising my CH from 230 to 350 as recommended by the “water balance for SWG” information page. I’ve had the CH at 230 for the past 30 days while the plaster was curing and just wanted to make sure I’m doing this preaperation correctly.

My readings as of yesterday are
FC=5
CYA=40 (will increase to 70 as recommended)
PH=7.6
TA=60 (will increase to 70 as recommended)
CH=230 (will increase to 350) as recommended)

salt levels are low around 2460 due to heavy rains and draining of pool.

I’m I on the correct path?

Welcome to the forum!

What is the pH, TA, and CH of your fill water?

If the CH of your fill water is higher than 100 ppm, you may not want to add calcium.

Also, do not mess with the CYA or TA. This time of year I suspect you can leave the CYA and the TA is fine.

Thank you mknauss for your prompt response. My fill water reading as as follows:

FC=.8
PH=7.4
TA=90
CH=170

I would then manage my TA and pH with your existing CH to keep CSI (Pool School - Calcium Saturation Index (CSI))) in the -0.6 to 0 range (what you want for a SWCG).

Great! Then I will leave my CH as is and maintain my TA and PH as instructed. The PH is the only one that I have really needed to manage due to the fresh plaster.

Thank you for your input!

Do track your CSI. If you use the Pool Math app be sure to turn on the tracking of CSI in the Settings.
