Pool opening water chemistry

[Nate1975]

I just replaced my vinyl liner and refilled pool to start this season. Just tested my water and am getting some off the charts high readings for alkalinity and calcium hardness.
FC is 1
PH is 7.2
CH is 2500
ALK is 2200
CYA is 0
I will add stabilizer to increase CYA, add baking soda to increase PH and will add proper amount of liquid chlorine to start slam. Have never had to mess with calcium hardness or alkalinity. Should I concentrate on getting FC, PH and CYA regulated now then worry about the others later? Should calcium hardness even be a concern for me? How concerned should I be about the ALK?

How did you get those TA and CH readings?

add baking soda to increase PH

Please do not do that IF your TA is high. All baking soda does is raise TA.

I have not yet added any baking soda. I have only added bleach and stabilizer so far. I was afraid to add baking soda as I know it also raises alkalinity. All the tests were done with Taylor K2006 test kit.

 

[mknauss]

So you counted 220 drops of R0009 reagent for the TA?

And 100 drops of the R0012 for the CH?

 

[mknauss]

Test the TA and CH of your fill water (tap water).

 

[Nate1975]

I have not added baking soda as I had read it increases alkalinity. All I have done to this point is add stabilizer and liquid chlorine. The testing was done with my Taylor K2006 kit.

Any chance you can answer my questions above?

 

[Nate1975]

Ok…after re-reading my original message that I unfortunately typed without my glasses and outside in the sun. I realize I added an extra 0 on the CH and TA. TA is 220, which is still much higher than it’s ever been. CH I guess is good. For some reason, I was thinking it should be no higher than 100.
So for TA should I just get the slam done and CYA up to 70 and recheck it at that point?

Only raise the CYA to 30 ppm until you can pass a Overnight Chlorine Loss Test

The TA will moderate as you add acid to keep pH in the 7's. IF the TA is that high, the pH will rise quickly. Test pH daily.

The CH is of no consequence as you have a vinyl liner pool.
