Been a pool owner about 6 years, learned a lot on this forum. Been SLAMming and fighting algae for over a month now. I seriously feel like Bill Murray in “Caddyshack” and algae is the gopher! Our pool floated couple years ago.. it does every year.. ripped at the drain. Pool guy supposedly order liner but apparently never did so we did homemade patch during pandemic. This spring, no new liner so still patched. Water is clear but every morning and evening I see what (I’m assuming) is dead algae along some seams and around part of the drain. So previously mentioned pool guy LAST time he replaced liner snd light ring.. “ oh, we don’t have the right screw to fit” So stupid us, okay it’s hanging on so it’ll be okay. Gap at top of pool light. So last week I realized maybe algae behind light. Took it out… brown/ black plume comes outokay… that’s the problem! Cleaned it, light has been sitting on the deck for a week. Nope… still can’t pass OCLT… help!!
