I'm hoping for some help here. We've been SLAMing our pool for about 5-6 days now and the water has turned yellowish and it's actually staining my white steps and it looks like the liner as well. The water has cleared up tremendously though, it was black when we opened it. I've had it at shock level or above (my husband dumped 5 gallons of pool store chlorine in when he shouldn't had) for almost a week. The deep end is dark and I still can't see the bottom, I can see the shallow end though. When I brush the steps the yellow doesn't come off, so I know it's not mustard algae. I was thinking maybe I had the FC too high and it could've caused it? I noticed the yellow about 3-4 days ago. I'm posting my most recent test results below, I know my TA is a little low but I'm not sure if that could have anything to do with it. Any help would be greatly appreciated! The picture (It's not the best) is my steps from this morning, I just went out and they actually look darker yellow now.
