I'm trying to clean algae out of the pool. I added algaecide a day ago and just added floc to assist with the process of clumping the particles to the bottom of the pool. After pouring the floc I remembered that I was supposed to put the setting to recirculate instead of filter. The floc instructions say to turn off the pump in 2 hours and let the particles settle. I have a sand filter and slowly poured the floc into the skimmer. Am I okay or should I do something instead of proceeding as if nothing happened (vacuum to waste after 12-24 hours). Thanks.
