    help with solving water cloudiness

    Hello
    After some weeks of steady rain a few weeks back here in Miami, my pool water remains cloudy. The pool is algae free, and looks clean, but the deep end looks mirky.

    TC 5.0
    FC 5.0
    ph 8
    TA 75ppm
    Calcium hardness 180 ppm
    Stabilizer 50

    These are the numbers from a local pool store that I do trust, and I added Calcium hardness and TA increaser AFTER. I also added 7.5 gallons of chlorine (3 jugs). The pump has been running for a good time (6-8 hours daily), but the cloudiness/haziness remains.

    What else can I do or check?
    Thank you

    Sta-rite cartridge filter
    Diamondbrite surface (i think. I am not original homeowner).

    What does the pool store say?

    My wife took the sample, and I am going to assume that she mentioned the cloudiness. Based on the numbers, they stated to add alkalinity increaser and calcium hardness.

    What your pool needs the most is muriatic acid. Your pH should ALWAYS be in the 7's. I would lower it sooner rather than later.

    I assume your cloudiness may be from the calcium chloride but you don't say how big of a dose you applied.

    Run your pump 24/7 until it clears and brush the bottom of the pool from time to time.

    I would have left TA alone.

    thank you Dave. So, they said to make an already basic pool (ph of 8) more basic by adding 5 pounds of sodium hydrogen carbonate? Wow.
    You stated that I added calcium chloride. When/how did I do that? I ask to learn, not to question or doubt.

    Trust in pool stores doesn't last very long on here... I bet their CH figure was off by at least 50% too.

    Re: help with solving water cloudiness

    the cloudiness is mostly gone. My latest numbers
    ph 7.8
    TA 75
    CH 225
    TC 4 and FC 4

    I am being told to add TA increaser, but I'm not sure with a ph of 7.8. I need some acid, right?

    What you need in a real test kit (see recommended) and do your own tests, then post the numbers, including CYA

    Ok. So in the name if education, can we assume that those are my numbers. A oh of 7.8 doesn't need more sodium bicarbonate. Correct?

    At the top of the page click on 'Pool Math' gives you all the recommended numbers for your pool.

    Correct. 7.8 is at the top of the scale, so anything higher and you want to use muriatic acid to lower as noted on the Recommended Chemicals link below in my sig. A TA around 70-80 is fine as well (if we assumed that was accurate). Once you obtain your own test kit, you'll see what we mean. Keep us posted.
