Adjusting my PH-TA and CH

[JB007]

its been 4 weeks since our pool was re-started after re-plaster with Wet Edge Prism Matrix - lapis blue. here are my chem readings today :
FC 3.0
PH 7.4
TA 120
CH 220
CYA 50
I want to get in the ranges recommended by you'll and need to know in which order i should adjust the chemicals.
Thanks for the help.

Those numbers are all fine if your results came from your own test kit and not the pool store. The FC is on the verge of being too low so I’d get some chlorine in there.

 

[JB007]

Yes, i was planning for the FC.
eventho the number look good, I wanted to get the numbers in the ranges that are recommended; PH (7.6-7.8); TA (60-80); CH (350-550) and take it from there.

If you are using the poolmath app, just add tracking for CSI and keep the CSI between 0 and 0.3. That will tend to keep all the levels in a decent range. As long as the pH starts with a 7, it’s perfectly fine.

Don't chase perfect numbers.

a pH of 7.4 is fine. You plaster curing will raise the pH on it's own. As it keeps going up you will then add acid which will bring the pH and TA down

The only thing I'd do is add calcium to get to 350 and then give it a little time. Right now your CSI is about -.06 and this addition would take you to 0.1

Ditto what Tim5055 said

What is the chemistry of your fill water? Are you on softened water for the pool makeup water? If you are on municipal water, I would take a reading of that so you could factor those numbers in. If you have hard water and not using softened water for the makeup, I would only take the CH to 300. It will continue to rise on its own with evaporation.

 

[JB007]

yes, tests are done in house with Taylor k2006-C.
Tap water is PH 7.2; TA 170; CH 230
do not have a softener or any filter. City water.

That's fine. Get some calcium in the water and keep an eye on things.

Everything is fine where it is

 

[JB007]

Cool. Will adjust CH to 325-350 and monitor the rest the. Thanks for the input you'll!
