I'm new to home and pool ownership.My pool is fairly large (not sure how many gallons) and I currently have a pool guy taking care of it once a week. I have a floater in the pool with chlorine tabs also. Two days after the pool guy was over my chlorine levels were a bit low. I had them checked at a pool store. The pool store is telling me its because my pool guy uses liquid chlorine and it evaporates quickly, and they want to sell me more expensive chemicals. My pool guy tells me that I have too much salt and calcium in my pool and I should drain and refill it because it is not holding the chemicals.
1. Do you guys use standard liquid chlorine or the more expensive powder? Does it pay to use the more expensive chlorine vs. standard liquid?
2. How often do you put chlorine into your pool during the week?
Is it normal that chlorine is added on Thursday and already low two days later?
Thanks for any insight!
