How to add or adjust chemical levels

[justlane4]

Thanks for responding so quick. I did fill out the entry form, hopefully that give you a better understanding of my situation. The cheap test strips that came with the pool are saying that the CYA is zero but I also have read how unreliable they are. I'm working on getting the recommended test kit but have one of the cheap Wal Mart Chlorine/Ph test kits. I am trying to keep the chlorine at 15 ppm like the chart says although i am just guessing that the CYA IS 0. Just bought 16 gallons of bleach to try and keep levels up for a few days hopefully that will work until I can get a better test kit. So just to be sure it's kill the algae, then adjust Ph, then adjust CYA all the while keeping chlorine levels between 1 and 3 ppm? Or can all the levels be adjusted at the same time, after the algae is gone of course.
