there is a brownish hair algea type stuff growing. not forming like previous cyano i've had. my tank is about 2 months old now. but i started it from a previous tank about a year before. upgraded from 30 to 65 with a 30gal sump. anything i can do to curb it? slow feeding a bit? fewer light hours? i have a tang and an angel grazing.. 6 snails and a hermit. good population of brittle stars and bristle worms so i dont think overfeeding could be a problem...
