Hi, TJ,

I would add two things today. Stabilizer (CYA) and more chlorine....don't count on the pucks to do either one...they're too slow.

Put in enough CYA to bring your pool up to at least 30ppm. It'll say on the container how much to add. (your pool is 19,000 gallons) It'll take a few days for the CYA to take effect but get it in there now.

Add enough Cl (at dusk, 'til your stabilizer takes effect) to bring it up to about 6ppm. For the first few days, you will lose ALL the Cl during the day so adding it at dusk will let it work all night before the Sun gets it.


Might have to adjust pH a little later but, for now, get that stabilizer in there and remember to add Cl each evening to bring your level up to about 6ppm.

You're off to a good start.
