Before you use "Yellow Out" make sure your PH is 8.0 & your clorine is normal. I listened to a rookie and found my pool without clorine after using Yellow Out. I shocked 3 times at the normal rate and finally doubled the dose to get the clorine back up. I changed out the sand in my sand filter last year (sand filter only 2 years old) with zeosand and replaced the pump. After this experience with suspended dead algae, I'm having a DE filter installed. In a couple of years it will pay for itself and save me work and grief.
