    Backwashing pool

    Starting this season going to BBB. I am a new pool owner, last year was the first year. When backwashing the filter will the borax in the water kill the grass??

    Welcome to tfp, pool603vac

    I have been backwashing my pool which has had 50 ppm borates for the last two years on my grass and it doesn't seem to cause a problem...however my grass was not great to start with. Doing a quick search of the site, I got this hit that has more users experiences with grass and borates (and chlorine);***-t1644.html
    TFP Expert who uses Pool School and my TF100 test kit along with PoolMath for my: Round 11K gallon AGP with deep end, 20" sand filter, Matrix 1hp 2spd, 6 2ftX20ft solar panels (and solar cover!), Intex SWCG (copper bars disconnected) and a Rubadub hot tub (chlorine). The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
