I'm curious to know if it is common practice to use BOTH liquid and tablet chlorine together. Also, I'm curious to know how much of each people use on a week to week basis. I realize that it would be different for any given pool based on a variety of things, but I'm still curious on what people are using and how much. I've been 'recommended' to use about 1 jug (2.5 gal / yellow jugs) of liquid chlorine and 2 tablets per week for my pool. I live in South Florida, my pool is about 11k gallons, and it gets a lot of shade. I realize that one cannot make an accurate recommendation without knowing the chemical readings, but since I'm waiting on my test kit to arrive, I can't provide that info right now.
