Just opened pool for spring, test result questions

I am also am amazed at the bogus advice given but the POOL GUYS.
Even "Dumb Luck" seems better

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.
