I continue to struggle with brownish dust that keeps settling in the bottom of my pool. I've read through a number of posts from the last several years with members reporting similar problems, but the posts never seem to reach a conclusion where the silver bullet solution is revealed. The pictures attached by wkener2 in this topic (http://www.troublefreepool.com/what-...ol-t35509.html) best depict my problem.
I began fighing the issue on 8/28 and brought my pool up to SLAM levels for several days, never failing to pass an OCLT. I even then raised it to Mustard shock levels. My water has remained clear throughout, but when I brust the bottom of the pool, this brownish dust poofs up and clouds the water until it resettles, generally in about 12 hours. I've added DE to my filter, but have had very little luck. Out of desperation, I even applied the pool store's recommendation of phosphate remover this past weekend (even though I was skeptical), vacuuming to waste on Sunday. Still, the problem persists. I once again SLAMmed my pool last night and passed another OCLT this morning. CC's are 0.
Has anyone had any final luck in ultimately getting rid of this stuff? I'll be closing the pool in a few weeks, but I really don't want to just have this same problem to look forward to in the spring.
