This is on my watch list. It looks like a great sump, great features, however, it does look a little like the quality of an Aquamaxx skimmer.
I've bought almost exclusively from MD for my saltwater needs, and have received great advice/reviews on equipment until I asked about comparing an Aquamaxx to a Reef Octopus. I was told they're very comparable, practically the same skimmer.
By that logic, a Toyota Yaris is practically the same car as the Dodge Hellcat.
(Anybody want an Aquamaxx ConeS, 2mths use?)
Back to the sump, if I can see one, and it's of quality, I'll be adding the 36'' to my new 180 build. For $600, I can't get burnt again.
