I'm building a 29g sump for 75g- sps reef. by the time I get my aqua c ev 180, bubble trap and return area done, there isn't much room for any live rock or plant life. I run gfo and since running it on another system my chaeto doesnt grow as well. I'm thinking of just throwing in some mangroves and a twist light in where I can. Maybe near the skimmer out area. Any ideas?
