Ok so... it has been 10 days and we have had rain storm after rain storm... I almost was there but now my chlorine level is 1...so after going through 8 gallons of bleach and still not being where I need to be...can I just pour shock in the pool??? what will that do???? can I add more bleach at a time??? my ph is 7.5 but I can't seem to get the cholorine level up. HELP!
