I know hair algae has been discussed in detail on this board. But I have a problem, I know some of my problem is a second sump with 4" of LS thats not working, I think its a nitrate factory instead. But I have a 4' CC skimmer run by airstones,. My main question is how much impact does the skimmer have on nitrate/nutrient reduction?? Should I invest in a new skimmer?
