Watermom is right about the poly.....don't waste your money.

YOU NEED MORE CL!!!! Sorry to shout but I want to make a point. Look at your Cl readings....not enough for even maintenance on a pool already clear!!

Try this stategy...If the direct sun is off your pool an hour before sundown, put in enough Cl to go to 16ppm. Remember it's gonna go down immediately...it may never even get to 16. Now go out just before you go to bed, test, and bring your Cl back up to 16ppm again....I'll bet you need to add a lot.

If you wake up around 4:00AM, you can do it again. If you wake up after sunrise, any Cl you put in will be quickly consumed.

You have got to repeat this pattern each evening. If you let your Cl slip back to it's current level......you get no results......that's where you are now.

Keep the faith and understand the process.....You are burning Cl at a rapid rate and you must keep it up there or you languish.....and get no progress.

Your other numbers are fine....you need Cl.

Have I mentioned you might add some more Cl?
