    Dosing acid... and Bleach

    I have a SW pool. The SWG is undersized for the pool - at 100% output it does not make enough FC. All else is good - runtime, all other chemistry.

    I'm going to start supplimenting with bleach to get the FC up.

    I've already rigged an acid doser to maintain pH, using drip lines & fiitings, plugged into the suction side of my pump. It pulls 5% (watered down) acid from a 5-gal pail whever the pump is running. Works like a charm!

    I'd like to set up a similar system for bleach. Any objections to mixing the two chemicals using a T-fitting into the pump??

    or would that just make chlorine gas, and blow up everything & kill everyone ?

    I can water down the chemicals to any 'safe' level. I only need maybe a gallon of regular stregth bleach a week.

    I would not suggest storing Bleach and acid anywhere near each other. While I'm sure you can build a good dosing device, one malfunction = kaboom

    Just my opinion.

    They need to mix into the pool water separately, never mix acid and bleach together before adding to the pool. If you are using a pump or injector of some kind for both acid and bleach the injection points need to be at least a foot apart.

    Just out of curiosity, what is your CYA ppm, and your FC ppm?

    CYA = 100ppm
    FC = 1ppm

    No issues yet but I'm walking a tightrope...
