Well my tank didnt appear to be dinos by somes opinions for the pics i posted but after cleaning glass on front and back this is whats now mixed in wife my cheato. The problem is i never see any strands with bubble on the sand or not really on LR either. I had some long snotty strands on back glass but i removed most a week or so ago with a scraper and mag float. Doesnt appear to come back like most have had but the sump looks ugly even if i do a lights out
