Ok every one thanks for all the help
My question is before I add the bleach to the pool should I back wash the filter to get some of the baqua out?
Next question I just ordered the tf 100 test kit but it wont be here till Tuesday. so i got a test kit at the pool store the clorine test only goes up to 5 is that parts per mill. If so how do I read 15 to keep the chlorine level at 15 over night ?///
