I know a little about maintaining my pool but just don't have the time so we recently hired a pool company to maintain it for us. I have heard how the stabilizer levels can rise from using the tablets and cause you to drain and refill your pool. The pool company told me that they come by once a week and do not use tablets, just liquid chlorine and that i did not have to add any throughout the week. Is that possible or am i being lied to because most people i talk to have to add liquid chlorine at least every 2-3 days?
