Hi,

I agree with watermom....that's more water than I would care to drain....especially since your numbers look really good. EXCEPT.....

You need Chlorine!!!! 4 gallons for your pool should raise you to 20ppm. If your water looks really nice after that, let your Cl reading drift on down on it's own and maintain your Cl somewhere around 7-10ppm.

Test your CYA a couple of more times during the summer and put in fresh fill water when it's appropriate. Your CYA will eventually (maybe have to wait 'til next Spring) come down on it's own into a more normal 30-50 range. You can then reduce your Cl level to around 3 - 6ppm.

(Those are good test results for a newbie....good work!!)
