Hi Pies I currently run a 7' x 2' x 2' with a single weir into a 4' sump where my skimmer is located. In my new setup I will be putting in 3 weirs and will be using my current 7' x 2' x 2' as the sump. The circulation is going to be done via a closed loop system and the lighting will be via T5's as I only keep Large fish and soft corals. I am also putting in a 20 gallon auto topup so the water level in the sump should remain constant as well. Mitch

Have done, thanks a lot Warren Also thanks a lot Pegasus for point me to this forum.

Hi Warren That would be great if you don't mind, I am currently running Autocad 2005 so that should be fine. Many thanks Mitch

Thanks of the info Warren. That gives me more confidence. I was originally planning on using a metal frame but could not find out any info on the web about how to make one, tolerances etc. Getting the material and doing the welding is not a problem its just knowing what to make. thanks again Mitch

Hi all Looking for a bit of advice. I am currently building my new tank 10' x 4' x 30" deep. I had originally planned to make the tank from Marine Ply, fiberglass with epoxy paints and set in the viewing pane from the inside. I have since found that a friend can get me the glass for the tank for the same price as the wood, cut and drilled. The glass is only 15mm thick for the front, back and sides but it will have a double 19mm base (38mm total). I intend to brace the top of the tank every 2 1/2' with 100mm wide braces. I have used the glass thickness calculator and it does appear that this thickness is OK and has a factor of safety of 2.63 on this size tank. I can reduce the height of the tank to 24" if nessary but I have already built the brick base 10' x 4' and have the RSJ's welded and in place to support the tank so those sizes are fixed. I am just trying to get a few opinions before I try it as maybe some else has done something similar in size and would like to share their experiences. Many thanks Mitch
