    Can't get alkaline down , new plaster pool

    Diamondbrite day 6
    ph6.8
    alk 220
    FAC 0


    im afraid to add more muratic acid because ph is getting to low, I'm afraid to start adding bleach till I get ph and alkaline right.

    what do I do?

    Aerate. That will raise the pH without raising TA.

    There's complete instructions in Pool School - Lower Total Alkalinity
    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.

    That said, you don't want to have an algae breakout with new plaster! Get some bleach in there quick.
    8,500gal plaster in-ground with attached spa, two floor drains, one skimmer. Chlorine, City Water.

    Yes, okay to use ALDI bleach. As long as it doesn't say splashless or scented. Just dribble it into the return stream so it disperses fast. If you're really worried, reach for the pool brush immediately after and make a few swipes to set up some cross-currents.
