Thanks, I'll begin daily additions and will be thrilled to be able to clean my glass. You previously suggested decreased lighting. This is a topic I've seen conflicting opinions on. Some say it doesn't help and blackouts can actually lead to dinos encapsulating and coming back when lights go back on. Of course I understand it is fuel for photosynthetic dinos. For now I've turned my overall intensity down to 10%,(normally 50-60%), and white and red to 10% of that. You didn't mention red so I'm curious about that? Another choice I needed to make was H2O2 or silicates, which again each seem to have their proponents. I'm starting with silicates although I'm not thrilled with now encouraging the diatoms I was hating just a month ago, ugh!
