Just received tf100 test kit question

[TravisMG]

No. Its really clear surprisingly. I've been filling it for a week

With TA that high, you should work on keeping pH on the low end to keep your CSI down. Otherwise, you will face possible scaling. Keep pH around 7.2-7.4 if you can. You will eventually make some progress on the TA with the additions of muriatic acid.

After adding my cya, and 1 gallon of 10% chlorine, my numbers are
FC 4.5
CC 1
PH 7.5
CYA 25, but still have some left in sock so that should put me at 30.

I work 24 hours tomorrow. So won't be able to do anything to it. Should I add 1 more gallon of 10% liquid chlorine tonight. And add the muriatic acid thursday morning?

 

[DeanP66]

That would probably be wise so you don't run out of FC and risk an algae outbreak.

2 days later, and after adding 1 gallon of muriatic acid.
FC 7.5
CC 0
PH 7.2
CYA 30
CH 0
TA 270

I added the muriatic acid 2.5 hours ago.

Thankfully your PH & TA were high, but did you use poolmath and/or pool calculator to get that amount of muriatic acid to add? That seems like an awful lot...

 

[TravisMG]

Yes. It started at 370 ta and 7.6 ph, pool math said to add 1 gallon of the percentage I used. 2 hours later they went to 270 and 7.2.

 

[splashpad]

Perfect! You'll have it inline in no time!

Am I ok with the 7.5 on FC, kids are ready to swim.

If you can see the bottom (safety), and the CYA is 30, I'd be okay personally

 

[IceShadow]

Yes - water is safe if pH is in the 7s, you can see the bottom of the pool, and FC is above minimum and below SLAM level. SLAM level at 30 CYA is 12. Swim away.
