    will cya hurt the lawn?

    Hello friends,

    I am about to dump some of my water to lower my 80 ppm cya level. I was wondering if I could use the water from my pool to irrigate my Saint Agustin lawn. I live in S. Cal and we are currently experiencing a drought. My FC level is at 2 ppm. PH is at 7.6

    Please advice,
    George

    Mine seems none the worse for several soakings. And get this - my CYA is now down to 90.

    I hope you let the chlorine run low intentionally just for this pumpout/lawn watering, because that's waaaaaay too low to maintain with CYA, well, anywhere.

    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.

    Soil bacteria (those that survive the chlorine onslaught, so migrate in later) will love the CYA "food" you give to them and will break it down to ammonia giving your lawn an extra nitrogen (fertilizer) boost though the quantity is rather low.

    Yes! that is correct. my intention was to lower the FC so that the water there will be less FC for the lawn.

    Thanks,
