My name is JJ and just moved in recently and am a new pool owner. Abit confused and am a newbie with water balancing and have been trying my best to keep the pool clean. I've been getting these black worm like things that collect at the bottom of the pool. They aern't a problem for the vacuum but would like to if there could be any way I could keep critters, bugs, worms out of the pool? And would like some help with water balancing. I went out and got the strip (water kit wasn't available locally, they said they would have to order it for now). I live in Canada and winter is on it's way. So would appreciate any tips/advice on pool maintenance and would have to close soon before the snow.
ph = 7.8
ppm free chlorine = 10
ppm alkalinity = 40
ppm stabilizer = 20
(that's all this strip shows, don't have any other values because I couldn't get the full kit).
