Hi All, I'm new to this forum, but have been reading some of the topics posted similar to mine and there has been some great advice offered - I am hoping to find my solution here!
We have a 24' Above Ground pool that was left full of water and uncovered this past winter (big no-no, I know). When we first opened the pool on Memorial Day weekend, we shocked it and everything was blue but very CLOUDY, when we vacuumed out the larger debris we noticed that there was sand (?) in the vacuum bag. Round and round we went with the pool store trying to find the cause of the problem, we've flocked it, shocked it, bought a $200 rover vacuum to vacuum it, raised the alkalinity, you name it - we've tried it! BUT our pool is still cloudy, and it's gone back to green since we didn't put the small tablets in after the flocking didn't work, and our vinyl liner feels like sandpaper.
So finally today I went to a DIFFERENT pool store and got our water tested by a computer and our results are:
Free Chlorine: 0.1 ppm
Total Chlorine: 0.4 ppm
Combined Chlorine: 0.4 ppm
pH: Over 8.2
Hardness: 200 ppm
Alkalinity: 81 ppm
Cyanuric Acid: 30 ppm
Copper: 0 ppm
Iron: 0 ppm
I am currently following their directions of: 3lbs pH Down (wait one hour), then 5lbs of Alkalinity Increaser (wait one hour), then 2 large tablets PLUS 4Lbs of Shock, run pool for 24 hours, add additional 2 lbs of shock...
Any idea if this will work? What should we be doing about the sandpaper liner?
