I would firstly just like to thank everyone that has made it possible for me and Meghan to keep and look after all these awsome creatures. The system used to consist of a standard 4ft tank with a standard 3ft sump. I was able to get a tank or two for cheap and moved over everything to the new system, with alot of help, beginning of October. The system now consists of a 150 x 50 x 40 display with a 90 x 40 x 55 refugium running into a 3ft fish holding tank and then into a 3ft sump with a Reef Octopus HOB 2000 skimmer. About 600l total water volume. The lights are two 250w metal halides with 2 x 39w t5 tubes.
