Hello, I am in need of help. I have been battling what I thought was a mustard algae problem for about 3 weeks. Slammed pool 2 times before over last 3 weeks and again last night. my stats are:
Brought FC level to 34 at 10 pm last night, at 6 am this morning it was 32.5 with CC of 0. While brushing this morning there was still puffs of green on stairs and shallow end. Every thing that I have read suggests that at shock levels like 34 mustard algae should not be present.I have brushed this pool so many times over the past 3 weeks that I wore out a brush. I am getting what looks like mustard algae on stairs and floor and also on sloped walls in deep end. I have read in forum that if its pollen it will be on floor only so that's got me confused. I have brushed very meticulously, no light fixture or main drain in pool. I removed ladder, and checked under treads and they were spotless, no algae. I also scrubbed skimmer boxes. Water has been very clear in shallow end, but cloudy in deep end from brushing what ever this is in pool. Any help would be very much appreciated!
