I'm having a custom sump/refugium built to fit in the stand under my 120. The quote for the work is quite a bit higher than I was expecting and I wanted to see if others here concurred. Basically, it will be two acrylic tanks about 19" x 21" and about 16 inches deep. The refugium water will flow through a bulkhead into the sump near the return pumps. The sump is pretty simple. A few baffles, but otherwise there is just space for a euroreef 8-1, a calcium reactor, two return pumps, and other miscellaneous junk. The price quoted was 299 for the refugium, 399 for the sump and 149 for a manifold to distribute water that flows down from the tank. This is about twice as much as I was expecting. Am I right or does the "custom" factor really add that much?
