I read that in order to kill algae you have to put in enough chlorine to bring the FC up to 30 - 50 ppm. I put in 9 gallons of Home Depot's 10% chlorine and that only brought it up to 15 ppm. So I went to Pinch a Penny and got 5 gallons of of their 12% chlorine and that pushed it over the edge. The next day the pool had turned from green to blue but it was so opaque I couldn't see the first step of the stairs. I ran the pool 24/7 for 4 days and it was still very cloudy so I turned off the pump let it chill until the ppm got down to 4 ppm so I could put in some clarifier. This took about a week to get there and I put in 3 oz for my 15000 pool. It said to run the pool 24 hours but if it wasn't clear after that to wait another 12 hours before adding another round. At this point the pool was still very cloudy so I cleaned the filter (single cartridge) and added more clarifier then ran the pool another 36 hours. The pool is still very cloudy and am wondering how long I need to do this or if there is a different product that is better than the Clorox clarifier. I have a polaris cleaner that keeps the particles moving around and I have been trying to brush the pool but I can't see the bottom to see if there are any leaves, etc. I'm curious to know a better, quicker, and more effective way to get clear water.
