Balance Needed for SWG

[Freakingout]

First time posting. We just got our new pebblesheen pool about 1 month ago, 30,000 gallons. They are adding salt tomorrow for the SWG. I am using the app to balance chemicals but the ranges change effective tomorrow and having trouble on what adjustments need to be made to keep a good LSI/CSI range (especially for warranty). We have kids and the pool gets used daily so lots of splashing! Temps are in the 90’s. Current readings using K-2006C and K-1766 for salt.

fC 3
Cc 0
PH 7.5 (this rises every day and must be brought back to this level)
TA 80
CH 210
CYA 35
Salt 300
TDS Meter reading 672

SWG manual says optimal salt level is 3,000 so with that said what do I need to adjust and where should I keep each level at?
Pebbletec says keep calcium 200-250, carbonate alkalinity 80-120 (this is different than total alkalinity correct?), pH 7.2-7.6, cya 30-80

Welcome TFP.
Adjust salt to the recommended level. Ensure they do not add too much salt.
Raise your CYA to 60-80. Then raise FC to follow the recommended level for SWCG levels
FC/CYA Levels
Raise CH to 250.
TA is fine at 80 - this will continue fluctuate because adding MA will drive TA down over time so test both pH and TA daily.

Thank you so much. I will adjust the CH and cya. Will also play with app to see what target pH should he with all the new readings to stay between -0.3 and 0.3 for LSI/CSI. That has been the biggest challenge!

With a new pool, it will require a lot of attention to the acid requirements. So watch TA as well as that decreases with MA additions.
Only use liquid MA with a SWCG, dry acid should not be used with a SWCG.
Try to stay slightly negative -0.3 to 0 to prevent build up on SWCG plates.

Thank you! I believe I will raise CYA, calcium and TA some and keep pH around 7.5 - 7.6. This looks to keep me in the -0.3 to 0 range.
