Green algae on bottom of pool

Postby Excursion7227 » Tue 06 Sep, 2022 18:39

I’ve been battling with this for three years and a later months of the season. My total chlorine is five ppm and my free chlorine is five ppm and even if I shock it to 20ppm my pool water still has green algae growing after vacuuming. I have tried algicide and when I dump it in it turns black. I feel like I’m wasting it. What is am I doing wrong? The pool is clear all season until the last two months when we don’t use it too much, then I get in there and manually vacuum it and I cannot get the algae to go away. Pool water was just tested phosphates for 100 and everything else was balanced except for high chlorine 18 ppm
