Well, I'm glad some other people have the same problem as me, but I'm sad that no one has figured out what the problem is yet. And that we all have the problem in the first place.Last year I had stuff in the same places as I'm getting them this year, in front of the shallow end jet, along liner seams, ripples in the deep end, and the slopes and curved corners of the deep end. The problem is that last year it turned out to be sand from the filter, and this time it's whatever it is.......Pollen?.........MA?. Anyways some good ideas on this thread, I took the removable stairs out and sure enough same dark brown crud under them......poor circulation and dark.........MA?, but nothing on the walls...Pollen?Today was the first time I've tested the water this year, although I've shocked a couple of times already.
Since the cya level is so low I figured I would shock for MA before I raise it. I added enough shock to bring FC up to 10 and will keep it there for the next few days.Will report back what happens. But if any one sees any thing wrong with this please let me know. Thanks and good luck to all with the mutant ninja algae or the pollen what ever it turns out to be.
