I had one setup under my 125g and even though it was over a third of the entire sump I didnt realize any benefits. From my reading and research I discovered that you really need a decent sized refugium to see results. In my opinion, save the money and effort and just up the water change schedule. I know water changes are a major pain, I have a half dozen tanks so I can feel your pain lol....but that is the best way to get your tank in order for corals. i dont do water changes every week, generally every month but I do extremely large amounts. On my 180g I will do over 60g a pop. Makes it easier on you and it's actually just a few more minutes to get that larger amount over say the normal 10%. I have a separate pump just for water changes and pump the water out of the tank and then use the pump to fill the tank back up. If your water change system is setup right the changes dont take that long. Beats using a bucket which is what I used to use. lol

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
