We have been very happy with our BBB treated pool. Our friends have been "pool stored" over and over again over the years. This year, they finally got fed up and fired the pool store and asked us to help them with the pool.
I wish I had pictures to show but in less than a week we turned a dark green swamp into a clear sparkling gorgeous pool by following the shock process outlined here.
We taught them how to test the water and they ordered all the appropriate test kits. Its been fun to see them get so involved in taking care of the pool! The pool looks better now than it has looked in years.
They have always struggled with reddish/brown staining - especially in the shallow end and on the fiberglass steps. The shock process did nothing to the stains so I tried a vitamin C tablet and it was miraculous. We've pretty much cleared up all the staining just with vitamin C tablets - either just by throwing them in the shallow end or scrubbing along the walls of the steps. I read the AA treatment process but am trying to avoid that for now as their kids want to swim RIGHT NOW. Since everything looks good, the water is balanced, and the stains are fairly well managed, do you think we are ok to just let it ride until close and then do a big AA treatment? They are so proud of the pool and I don't want to take another couple of weeks to drop FC, do AA, bring FC back up, etc.
What do the experts say?
Also, we haven't officially tested for metals - but since the vitamin C did so well I just assume it is metal staining. And by the color I assume it is iron. We haven't added a sequestrant yet - Jack's Blue stuff the right one for the job?
their pool details -
oval shape - approx. 20x40 size -estimated 30K gallons
very shaded yard - only gets around 3 hours of direct sunlight a day
Thanks for any suggestions!
