Well the start off I have a 20g high with a 10 gallon refuge. I have noticed my coral dont look as good as they could look and was wanting some input from you guys on this subject. I have a little hair algae issue but other than that nothing to major. For lighting I run 2 panaorama pros(@ about 65%), for filtration I have a nano tunze skimmer, filter sock with a thing of carbon in it, I also have a ball of macro algae but always has a film of red algae on it every damn day! I feed my 3 fish (6 line wrasse, 2 snowflake clowns) every other day pellets. I don't have my params as of right now but can give you guys that when I get home from work. Any info is appreciated
