Calcium Hardness reads 420

[wantobpoolmaster]

Just wondering how concerned I should be with my hardness reading 420. Everything else seems to be in order. (Salt system with a plaster pool)

FC-4
PH-7.5
TA- 80
CYA-60
CH-420

Thanks

It's at the higher end of "doable" but "doable" nevertheless.

I would make a note to monitor pH and TA carefully all swim season, not allowing your pH to get much over 7.5. That gives you pleanty of "fudge factor" and you will never have an issue. Do you know the CH of your fill water? If not, test and post that up.

Thanks I'll put up those numbers tomorrow.

Just keep a close eye on your pH and don't let it go above where it is now.

By keeping your pH low your TA is liekly going to come down too.
