I'm in week 3 of acclimating my 72 bow to new lighting (from 230 w of PC to almost 700 w of MH/PCs. Noticed a few spots of brown stringy algae in some low flow areas. Its the first algae I've had in 8-10 months. Showing no detectable nitrates or phosphorus. Could the lighting have kicked this off a bit?
