Hi everyone so I have been running my ATS for about 3 months and am still learning more about them. Yesterday I cleaned one side of the screen under warm tap water and let the algae sit out for about an hour bc I was cleaning my sump. Today my algae I left on is turning white and I'm guessing it's bc I left it our for to long, also Idk if I should scrape all the left over algae that's white but then my screens will be bald. What shall I do guys?
