I battle black algae every year at the beginning of the pool season it seems like with my pebble surface (probably due to cold weather FC neglect). I have my FC elevated and I am performing manual brushing.
I normally run high speed for about 3 hours, and then low speed anywhere from 5-8 hours to maintain a TFP salt water recommend FC level in the early evening. Should I be increasing my low speed pump time to promote greater water flow over the black algae areas throughout the day? Or does pump run time not really matter as long as I'm maintaining an elevated FC all day?
