Volume is 14,000 gallons. New liner, new water 2 weeks ago. CYA was 0. Added 4 lbs stabilizer with sock over return almost a week ago. As stated above, dot starts to disappear around 40, but is still visible filled to top of tube. Bought a floter and have pucks left over from last year. Have not started with the pucks yet, was planning on starting this weekend. Does the pump need to run while the floater is in the pool?
