Hi, we're starting up a Red Sea Reefer XL 300, although we have the Red Sea Skimmer 600, so the refugium would only be the smaller compartment (otherwise the skimmer doesn't fit). What lights do people recommend for that space (approx 8.5" long, 4" wide) that aren't too expensive, and aren't cheap unbranded knockoffs that can only be bought online. We were looking at the Tunze 8831 lights, but they are a little bit too long for the space and would get in the way of changing the filters.
