The refugium and sump lines from Aquatic Design Habitats Inc. (ADHI) are some of the best acrylic sumps available in the U.S.A. and we’re not just saying that because they are our newest sponsor. The berlin and refugium sump models are made in Arvada, CO and they have been a popular choice with public aquariums and institutions for over four years.Â After personally having used these sumps almost exclusively over the last 3 years on dozens of tanks ranging from 50 to 1000 gallons, it makes us scratch our heads and wonder why there are no Name Brand sumps in the marine aquarium industry. Aquarists often tout their Tunze or Ecotech Pumps, their Ushio and Radium bulbs, their Euro Reef, BK or ATB skimmer and even their tanks get the name brand treatment but we rarely talk about what kind of sump we’re using. With it’s complete plumbing kits,Â reinforced bracing, well sized chambers and the practical design, we’d like to see ADHI sumps become one of the name brand sumps. The refugiums also include a durable power compact light, a primary chamber for in-sump protein skimmers and black dividers which keep light from spilling out and growing algae in unwanted areas of the sump. The ADHI Refugium 20 retails for just under $300 and the price goes up from there. The sumps are available retail from various online resellers and vendors can learn more about wholesale pricing and their drop ship program by contacting ADHI directly.
