What if CYA is 53ish?

Paul:
Evan didn't tell you anything that contradicts my advice. That's why there's overlap.

I look at the CYA range, and the matching residual chlorine range, and try to match my residual to whatever end of the CYA range I'm at. So if 30-50 is 3 to 6, I prefer 3 for 30, 4.5 for 40, and 6 for 50. It's not hard and fast, probably isn't even necessary, but it works for me. Either way, you're at the high end of the 30-50 and the low end of 60-90. So use the residual levels for those ends of each.

Just don't get confused by it. It just SOUNDS contradictory.

Carl hit it right on the head again, as usual!

If you get LOTS of rain (in the last two weeks I have had to get rid of approx 4 inches of water from my AG pool ---not to mention the little refills I needed to keep my water levels up after kids in there and the heat) should I add more stabilizer???? Cause of all of the rain do I have to shock my pool water? It is clear and all of my levels are fine

I tested my CYA and it went down from 60-ish to 40-ish(now).... I have a WHOLE FREE HUGE bucket of trichlor tabs so I was thinking if using them now that my CYA is lower (as I know they add it to the water). Does anyone know how much CYA the tabs will add or how often I should check the CYA?????

Thanks

IF you are planning on letting the water evaporate I wouldn't add any more becuase it will concentrate as it evaporates. If you drain some of the water out then you might want to consider it if it made your stabilizer go below 30 ppm. Since you drained some water you have diluted the CYA however a staibilizer reading of "40ish" is ,IMHO, perfect!

Thanks, Carl for the advice on my "chlorine range." Its at 8 right now and I'm going to let it drift to 5 before I add more bleach.

The pool looks great thanks to the advice from you, Evan, Watermom and all the other people willing to share their knowledge. This is a great forum because of folks like you.

Warmest Regards,

Paul

If anyone even suggests a group hug I'm outta here!

seriously, this is what the forum is all about and we all should give Ben a big THANKS for putting it together for us!
