Aussie Reefer here, been shopping around for a 6 foot peninsula style tank setup to act as a room divider
Had a look at the Cade/Waterbox options but always wished their cabinet stands would be a touch bigger and wider for more room to work around.

So decided to DIY the cabinet using mix of 8080 and 8040 aluminium profiles. Stone slab for some appeal.
Cabinet 2310mm L x 810mm W x 1120mm H (sized this bigger then the tank so there's a ledge to put stuff on)
Tank size on order 1800mm x 700mm x 600mm.
Whole thing is on 8 heavy duty castors with load capacity of ~750kg each. figured this will be plenty.
Not that I want to move this around once it's set in place..But figured if the need arises, I can.

Sides and back panels in progress, done in marine ply, in the process prepping for paint.
Panels are all attached to stand via magnets, so each individual panel can be removed for easy access.
Doors will be all windowed, not sure whether to use glass or acrylic.....to be decided.

Plumbing next.....still deciding on whether to get a custom sump or use existing.....Hmali would be nice :)

Dude, that looks awesome
 
Following along! That stand looks amazing! If you are going the custom sump route, who will do it for you?
 
Been a long time between stumps...and finally the sump arrived today....doing a quick leak test and roughing in the plumbing.
Don't you just hate it when you thought you got all the plumbing pieces ready to go only to find out you needed a few more pieces... lol

Now the wait for parts to arrive

Love peninsulas. Mine is 96x36. One of the biggest improvements I made to my tank was relocating the returns. My display is custom and the returns were designed to exit the overflow box and into the display. I ran it that way for a while. I put a wooden airstone in each return pump and quickly noticed that many of the air bubbles simply went right now the drain. So I relocated both returns to the display/short side of the tank. This made a massive difference in water clarity and stability. You can see this some place in my build thread.
