Just opened pool for spring, test result questions

[conductor500]

I have looked at a couple differant pool stores and no luck on finding the CYA reagent. I am going to order the kit off this site since I have been attending school here. The one store stopped short of telling me that the CYA was not important (maybe I was just reading too uch into it.) It would seem a "pool store" would have all supplies on hand this time of year. Anyway,since my pool has been exposed for 24 hrs. my ch. is dropping ( istill havent added anything as of yet) Ph stable at 7.2 and alk is still at 120. My next "Q" is I will leaving for 4 weeks and I am going to put the solar cover on untill I get back and wanted to know how much I should raise my Ch. before I leave?
My wife will be here to keep check on it while I am gone. Since I don't know my CYA levels will this be a problem?
Hey Dave, about that liner. If you live in Atlanta I will be there for 4 weeks come monday
Thanks for the schooling guys.

P.S. My pool is a 27' AG. Is that 16,500 gal? Need to know for use of the handy dandy bleach cal.

Ok, Just got my CYA from the pool store.
Here are my readins..

CL. 3
Ph 7.4
alk. 110
CYA 90

I found this pool store owner very helpful. She did say my CYA was a little higher than it should be and that the only way to lower it was to drain a little and add more water. But she didn't seem overly concerned about it.

Your cya reading is higher than I like and like the pool lady said, the only way to lower it is to do a partial drain. I like my cya reading to be between 30-40. If you decide not to do a partial drain, you can live with cya of 90, but you'll just have to run higher than normal chlorine levels as a result to avoid an algae bloom. See the chart at the following link. Ph and alk look good.

One thing the pool lady said was that CYA at high levels has been known to possibly cause some health effects. Any truth to that? I live in Ky and supposedly the public pools are not allowed to use the stabilizer. CYA

With a CYA of 90, a chlorine level of 3 isn't going to be enough--you need to up it to at least 5.
