I've been having an issue with my across turning brown. The polyps are out but they don't have the coloration they should under my T5's. Well, Greg lives near me and brought the par meter by and at the top of my rock it was only 250. My montiporas are thriving really well but the Across not so much so my question is does.anyone have any experience building Led's? I want to add a couple of strips to supplement the T5's.
