My algae issues

Since you have no CYA, or very little, it is ok to go ahead and use dichlor shock and trichlor pucks for awhile, but monitor the CYA level periodically or else you may end up with too much. Until you start to get some CYA built up in the water, you may have to add bleach morning and evening. Once you start to see a CYA reading, you'll be able to test and dose in the evenings only. You asked if you could swim with cl at 20 ---- that is pretty high but with little cya, it won't stay that high very long. it is probably ok to swim but I think I'd wait until it came down some if it were me, maybe to 10 and then I'd wear an old suit. You really don't want to take the cl that high as it may bleach out your liner. I wouldn't take it any higher than 10 right now. Keep filtering and hopefully the haze will soon be gone. You're almost there ...............

EDIT to add: Dichlor adds 9 ppm for every 10 ppm FC added and trichlor adds 6 ppm for every 10 ppm FC.
