    Cal-Hypo cloudying pool

    I added some cal-hypo last night to raise the FC because it was very low so i added a bit too much,i think 26 oz.so i predissolve it in a bucket then threw it in the pool and in a few min the whole pool turned cloudy and it always happpens when i add Cal-hypo.

    Wondering why and how long can it take to become clear again?

    BTW: i have about 11 lb of Cal hypo ,it's the pool shock from IN THE SWIM

    Re: Cal-Hypo cloudying pool

    Cal hypo can cause clouding. It is more likely when TA and pH are off. Your CH is going to go up very fast using Cal Hypo in a pool that size.

    That is not uncommon. How long has it taken to clear up in the past?

    Re: Cal-Hypo cloudying pool

    I'm now seriously thinking of going with bleach,but whole family is scared of swimming in a pool filled with bleah.i already explained that it's the same chlorine as the tablet but they won't listen

    Also this year instead of buying some expensive alkalinity increaser at the pool store i just went to the grocery store and bought four boxes of baking soda for half the price

    Just don't tell them you are doing it

    Maybe this pool school document will help?: http://www.troublefreepool.com/pool-..._chlorine_pool

    Re: Cal-Hypo cloudying pool

    Calhypo = method of getting bleach (chlorine) into the pool
    Trichlor - method of getting chlorine into pool
    dichlor - you get the idea I'm getting at.

    Go to the pool store and ask to see a bottle of liquid shock. Note the ingredients. Now get a bottle of Clorox, and read ingredients. Make sure the family gets to read them.

    Chlorine is an element. You can't change that, unless you have a super-collider nearby.

    Re: Cal-Hypo cloudying pool

    SWG becomes valuable when you travel. It is a way of keeping your FC up at all times even when you are not home.

    It will be fairly easy for you to keep enough bottles of bleach around. My pool at 10x the size of yours, was a pain. Buying pallets of bleach wasn't fun.

    Re: Cal-Hypo cloudying pool

    I really like my swg, but I would recommend you start with bleach/liquid chlorine and then see if you still are interested in the swg.
