The pool is about drained to where the shallow end is showing, I am going to go vacuum to waste while the water is lower since it will be easier. I will get everything cleaned up nicely, then begin to fill back up keeping chlorine in it. I will get a new CYA reading when full and go from there. How the hell did the pool store say it was at 30!!

Water can't cost as much as the 50+jugs of bleach I have dumped in this hole in June. I retested the CYA it is actually over 100 past any form of measure I would guess 110-130. I have had that high of chlorine in it for awhile and the green color is still there it hasn't even faded out blue yet. This has to be the CYA not allowing the Chlorine to work isn't it?

Well I bought this house in June of 2005 and just did what the pool store said for the rest of that summer. In the winter I read bout BBB etc.., but was too lazy to look into it further. After a much higher then expected pool cost (go figure) the summer of 2006, I was fully ready to implement the BBB. I opened the pool and had it clear with in days and it was going great. I used up some Chlorine tablets I had left and started in on the bleach. I left on a four day trip and came back and the pool was cloudy. I hadn't gotten a test kit yet so I still relied on the pool store and their wonderful Biogaurd software and color strip coumputer test. I have been literally dumping bleach in this pool and nothing has happend, I kept going to the pool store and the test all looked good. My own test kit finally came and I did my own test. I should add that their test had my CYA at 30 and I wanted it a little higher so I added 4lbs or Cynuric Acid. I don't know what their test was doing, even after I added the stuff it showed CYA 30. My first test of my own shows the CYA at 90-100! So I was already high and then made it worse. Curently here are my numbers FC 30-40ppm CC 0ppm TC 30-40ppm PH 7.4-7.5 although this is probally worthless right now with TC so high T/A 170 CYA 90-100 So the whole time I am wondering what is wrong cause I didn't think I had mustard algae, well know I know my CYA is so high it is killing me. My pool is a 30,000 gallon concrete pool. I am going to get some Polyquate or whatever and add that to try and help, but I refuse to spend the money on the amount of bleach it will take to keep my TC where it needs to be with this high of a CYA. I need to at least cut it in half so do I need to drain out half the pool!!!! Any help would be great!! At least I wasn't buying pool store chemical and feeding their pockets by just burning up Chlorine Thanks
