changing pool water

[aylad]

You can try using more chlorine, but you're going to have to keep it in the 8-10 ppm range at all times (that's for 100+ CYA), and even that may not be enough. It might help if you use some polyquat 60 as well. No guarantees, but I guess it's worth a try. You do need to stop using the tablets, though--they are raising your stabilizer even higher and soon the CYA will be too high to compensate for even with high chlorine--if you're not at that point already.

Janet,
I am using stabilized chlorine tablets.

If your CYA is that high, you need to quit using the stabilized tabs and switch to liquid pool store chlorine or bleach, or, the CYA level will continue to rise.

Hey, I've heard that before!!

Yeah, I know. Probably even 2 or 3 times before. (More likely 2000 or 3000 times before!!

How you don't algae and scaling with those numbers is kind of a miracle.
CH 1000?
CYA 300?
TA 240?
FC 3?
TC 5 ?
(therefore CC=2)

Your FC needs to be AT A MINIMUM 8ppm and you need to shock the pool to 25ppm just to get rid of the CC.

You also need to go through the TA lowering procedure--with your CH at 1000, I suggest you follow Chem_Geek's and Waterbear's usual advice about getting TA down to around 50.

Draining and refilling will help get those out-of-control #s back in control, but not if you are going to continue to use tabs. Right now, the ONLY forms of chlorine you should be using are bleach/Liquid Chlorine. Lithium Chloride would be OK but it's insanely expensive.

Good luck!

[boscoe]

ok, I'll try the polyquat60.

I might drain it sooner than November,
thanks

Change water??? I've had the water in my 20x40 IG pool for 14 years, and yes believe it or not it is still wet!

just for fun, last week I took a water sample to 3 different pool stores... and got 3 different results. whoda thunk it
