    Added 58% Calcium Hypo - pool went cloudy

    The pool has been on the Clorox bleach only diet for about 5 weeks. It looked great. My CH was at 225 and I want to get it up to 300/350 range. Since I have several left over pounds of Calcium Hypochlorite 57.8% I thought I would just use that for a few days instead of Clorox to treat the pool and raise the CH. I only added 2 lbs and while I can still see the bottom of my pool it went cloudy for about 24-36 hours. Is that to be expected since it really hasn't seen anything but bleach for 5 weeks? Also, is there CYA in Calcium Hypo? Thanks.

    Probably, Calcium Carbonate?

    This morning I'm at:
    FC = 14.5
    CC = 0.00
    pH = 7.8 (I'd like to lower it, but I don't know if accurate due to high FC)
    TA = 170
    CH = 225
    CYA = 30

    Yep, probably a cloud of calcium.... you really need to get that TA down, some....probably by half or more. Why so high a chlorine level? You can be pretty sure that the pH is not accurate and won't be until your Cl is below 10.0.

    Pretty common phenomenon.
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Richard thanks for the link. I should have figured it would be out there...I'm sure there's not much you guys haven't seen by this point.

    ewkearns...TA too high? Okay. I just remembered that I typically target 150 bc the "pool store" kind of set that number in my head years ago. I now see it should be in the 70-90 range. Regarding pH though; once it FC comes down tomorrow or next day...is 7.8 okay for plaster as it notes on recommended levels; or I see a lot of forums where people are targeting more the 7.2 range.
