I found it was definately water flow I moved my MP40s lower as I had cyano on the sandbed, once I did that it cleared up quickly, but then started higher on rock workj. moved MP40's backup and its all gone, even on sand. I also increased how powerful the mp40s were pumping during the day.
I do have chemclean onhand and have not used it in the last 3-4 months i have been experimenting with flow.
