Hi all, Thought I'd start a new thread for my tank and let you all know the details. So we just moved house and in the process I decided to get rid of the old wooden cabinet and tiny Sump and replace it with a new metal stand and a new sump. I put some thought in the new sump and made it about 3 times the size of the old one and added a compartment on the end for RO water with an auto top up. I have also included a compartment for a DSB and Cheto/ Algae, but I haven't set it up as yet. Right now enjoying the extra water volume. In addition I have finally installed my new Metal Halides, which I mounted from the ceiling. They are 400w MH with Giesemann lamps, MEGACHROME coral, 14,500k. Huge improvement from the T5's that I previously had. Thanks @bryan from Jungle Aquatics for sorting me out with them Total water volume is 750 litres Display tank Dimension 1.8m x 0.6m x 0.6m I'll measure up the Sump this evening and post it here. Had an out break of white spots and lost a few fish and corals before they went back in the tank, which was very sad, but since we have put all of our fish and corals back in the tank and all is looking good. White spots are nearly gone and even our sick scopus tang is starting to look a lot better now. I think all of the stress and changing water parameters put a lot of stress on them. The worst is behind now and looking forward to getting our Ocean back to its former glory. Pics to follow.
