Hoping to get some good advice. Current issue is with white flakes floating around. Just cleaned the SWG last night. Pool is 1 year old PebbleSheen. Not much buildup on blades of swg (Pentair IC-40). What’s the best way to combat? What should I add? Gonna get water tested tomorrow. No numbers right now. Is there a graphic out there that helps explain the interaction between chemicals added to pools? It gets pretty ugly trying to grasp it all in words alone. Thanks in advance.
