Hello friends. Need help again. Have learned so much from you all and was feeling pretty proud of taking care of my own pool for the first time this summer. Readying pool this morning for guests and found THIS on bottom of pool, and when I scooped it with the net my heart sank!!! Ugh!!! See photos. Greenish yellowish brownish and slimy. Clearly algae.
Background: Have been battling Iron stains (did the polyfil and MM treatments which work great and still keeping FC in ideal range) , and what I thought was just dust and debris, but after reading several “dust in pool” threads in the wee hours this morning, started to get a bad feeling...
I have already Slammed twice this summer, properly I thought, passing all 3 tests each time. Cleaned ladder and around light. Brushing every day. Dolphin robot vac almost daily. Testing chems every day and keeping FC on the high end for my CYA after my July 4 SLAM episode. FC usually 5 in the morning and I add enough 10% bleach to get to 7. For a while I thought the “dust” was coming from the returns...Nope.
This morning I started SLAM, backwashed and recharged filter, and am hoping to get it right this time. What have I been doing wrong? Thanks again for all your help and support.
