    Woops, let my chlorine get too low

    I got distracted from my new pool and inadvertently let the chlorine get to 1, with 0.5 cc, and pH 7.8. I have been diligent about keeping pH and TC in range since it was installed in the spring. How bad have I fouled up?

    In response I added 374 oz of Chlorine to get to shock level, and about 12 oz of MA liquid (the last of both on hand) and then brushed the pool. I plan to leave the filter on low all through the night. I wont be in a position to tend to it until tomorrow afternoon.

    What do you recommend folks?

    Built 2012: 14x28' free formed IG gunite with 4 person spa. 11,000gal, Hayward 2 speed Tristar pump, Hayward 420sq ft cartridge filter , auto tablet chlorinator (I use BBB), 250BTU Hayward heater, quartz pebble finish, LED lighting

    If it was just one day with FC too low, you probably took care of it. And then some.

    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!

    I think you handled it well. We all have an oopsie, got too busy or forgot moment once and awhile. You acted quickly and gave it a good dose of prevention. You might have been ok with less, but you insured yourself with some extra. Nice save
