Some of you may know me from some of my previous postings about issues with iron. We have 4500 gallon indoor Endless Pool (which we are now calling the endless headache). We have a well and have had iron issues from the beginning (last August). I've read every metals post on this forum backwards, forwards, and inside out. I've tried every recommended remedy - all to no avail. We have yet to see blue water. We even went to the extreme of installing a DE filter (the pool came with a cartridge system) so we now have two filters running. We also drained the pool as far as we could, which is only about halfway because we have a large extra deep section and Endless Pools advises not to drain any lower than 6" from the standard depth to avoid liner sagging issues. We filled again with a metal out filter. Still brown water. Went back to the pool store two weeks ago out of desperation. Bought more Pool Magnet, some Sparkle Up, Calcium increaser, etc., etc., to the tune of $100 plus. Water still brown. Readings are:
Calcium Harness: 135??
Total Chlorine: 5
Free Chlorine: 4
Cyanuric Acid: ???
Here's more of the craziness. My Taylor test showed no calcium hardness when I went to the pool store, and her computer test showed the same, so she had me add 2&1/2 lbs of harness increaser. A week later, my test still showed zero. So did her computer test, but then she tried hand testing and got 135. When I first went in, my water tested 1.6 for iron. Next time it showed 2.6. They said that was because the iron was now sequestered??? (Water just as brown.) told me to keep adding Sparkle Up and wash out filter every 24 hours. Next time I went in, iron 1.0. They said this was because Sparkle Up was actually pulling the iron out of the pool. However, pool was still brown, and Sparkle Up coated filter was white as snow every time I washed it out.
My test also shows no cyanuric acid (hers doesn't measure for it) even though I added cyanuric acid as per this forum's recommendation about a month ago.
By the way, I've also got two CuLators in my filter basket. Obviously I now also have a combined chlorine issue, but raising the chlorine level is only going to turn the water darker brown. I honestly don't know where to turn at this point. All I want for Christmas is blue water. Help!
