Dirt on bottom of pool

Good morning all, my pool sets in back yard surrounded on 3 sides with trees.
I get some dirt from wind, rain and so on. If I don't vacume pool within a couple of days
bright green (algae?) will appear on some of the dirt streaks. Water is crystal clear.
Vacume and all is good. Can I use an algaecide to stop this?

Sorry, this should have been in algae section.

I just brought my pool to SLAM level of FC 16 by pool math. Do I keep it there just long enough to pass the 3 rules, and wait to see what happens when new dirt that falls to the bottom? Thanks Bill

Once you pass all 3 criteria, keeping your FC in the recommended range will help tremendously in deterring algae. Dirt isn't algae..........(but can pick up a stray traveler or two). If it was, my pool would be solid green due to some road work behind my house--tons of dirt hauling going on. Back to vacuum!
