I call my sumpless tank sad since it's nowhere near as nice a set up as many featured here on this fine forum. Not big on difficult to keep sps. I love it as a hobby, but my 77 Hagen will never be a candidate for TOTM. An upgrade to custom peninsula with basement sump has been planned for many years now, but I have other hobbies & home renos eating up $$$s.

Even if they don't work out for you, you'll only be out a few bucks & they can be used elsewhere. Various versions of these have been around in local stores for some time now. I have no doubt they all come from the same country, but local vendors & distributors take a huge mark up.
