Hi all. New here. We made the mistake of covering our pool this winter (never again) and ever since it's been nothing but problems. We uncovered it and super shocked the dark green water, all was fine. Water cleared up nicely but the pool steps turned rusty brown. After much research, discovered it was iron, so we used Pool. Magnet Plus and Sparkle Up according to directions....PERFECTION! All was great for a week, yesterday it looked like toilet paper all in the pool and growing on the steps. I figured out that was white water mold. Not completely sure how to remedy that situation, so I super shocked yesterday and this morning woke up to no mold floating around, but brown steps again. I'm losing it it! Please help!!!!! What am I doing wrong?? I appreciate any advice.
