I wanted to ask if this seems about normal for this phase. I'm posting a few photos to get an idea of the overall system. In particular, I'm wondering if the red/purple is of concern ? It started Brown then green but now mostly what you see. The sandbed seems less affected perhaps with the snails. The refugium is growing all sorts of algae with some hair algae showing up about a week ago. Salinity 1.026 Nitrate is steady at 20-25, Phosphate has dropped to .10 and temp kept at 78. Thoughts ? I've only been lighting the DT for a couple hours at feeding times and only a HF LED shop lamp.
