Yes, agreed. I wasn't planning on adding anything other a little bit of chlorine during the exchange process until I test and get a baseline.
Extremely high combined chlorine
- Thread starter rmb212
- Start date
Haven't replied yet with results due to some unexpected events but did get the water exchanged and rebalanced.
As of today:
PH 7.5
FC 9
CC 0
TA 60
CH 75
CYA 60
Salt 3800
Salt generator has been on lowest setting for about a week now. Calcium was present in the fill water none was added. The question still remains should I increase the calcium hardness since I have a border tile and if so to where?

Personally I’m not a fan of adding calcium ever but if you get significant rain solution and your fill water is really soft you can add some. I wouldn’t add more than 100ppm extra and I would only do it in small batches. Calcium additions can cause cloudiness and haze in the pool water that can take several days of filtration to resolve. To avoid it, add it in small quantities and perhaps adjust the pH slightly lower (7.2) to ensure that the calcium has high solubility.
Another way to add calcium is to use cal hypo for chlorination. It too can cause cloudiness but at least you get some benefit from adding something you need anyway, Chlorine. Every 10ppm FC from cal hypo adds about 6ppm CH.

I didn't test fill water directly but first test before rebalancing was:
ph 7.2
FC 2
CC 0
CH 75
TA 30
CYA 0
Salt 400
I did add a little liquid chlorine here and there when filling. So prob just leave the calcium where its at?

I think going up by 100ppm would be more than sufficient. You don’t need (much) calcium with a fiberglass pool and ceramic tiles are not affected by low calcium. The grout is reported to be epoxy so there’s no issue there. You simply need some calcium to inhibit foaming in the water of someone with lots of soap residue on them goes swimming. 50ppm CH is sufficient to inhibit foaming. So it’s really a non-issue in your case. I wouldn’t stress about it.
