Help! Our pool is still green after shocking!
We we bought our house as foreclosure 9 years ago. Initially, we used tri-chlor and di-chlor, then went to a SWP. Loved our SW pool! Well, cell went bad then board got struck by lightning. Last year, we went back to chlorine for $$ reasons. Pool turned bright orange when opened (shocked) for summer. Got orange out of water, but could not get off liner or anything else. We found info on your site about using citric acid and followed directions. Worked! This year, we went out of town for 1 week. Hadn't opened pool, but was not covered over winter. Came home to green, green pool. Shocked with di-chlor since CYA not high. Wrong idea. Faint orange ring on fixtures and around pool. Yikes! not again. Started researching.
Today, I decided to SLAM pool. No more tri-clor or di-chlor. Brushed down pool, backwashed. CYA very high, but read where someone had theirs around 200 and still used bleach to rid algae, ours is 120. Used FC -CYA chart and figured need 7 bottles, 2quarts of 121 oz, 8.25% bleach. Brushed pool again, backwashed, added 8 bottles of bleach. Waited 30 minutes - tested FC. Yikes! I could not get the test to turn back to white. By drop 72 of R-0871 the color turned dart violet, well, kept counting and swirling. I got to drop 90 and stopped. Ridiculous to continue.
At this point, I don't know what to do.
I would be so appreciative of any recommendations!
Found your site last year, it is awesome!
