That famous line from the appropriately named "The Money Pit" movie comes to mind.

But after MACNA, I'll be getting my 400g back into the house at last. Here are some pictures from the water test that I received today.

This time the tank has Starphire glass on all three sides, the overflow box has the black trim wrapped around it completely, and the black acrylic panel that hides the external overflow has a gap on each end to avoid pressure on the front and back panel of the aquarium. All four walls are 3/4" thick glass. Time to round up some minions to help carry it inside the following Saturday.

    Marc,

    I am in design phase of a eurobraced 12mm 66"x24"x22" shallow reef. Will have external overflow box similar to your 400g. I wonder why they don't extend the long Eurobrace pieces all the way through to the outer edge of overflow box? Gives silicone surface to top of box. It would add strength to the box and not prevent access to durso's? I think it would also reduce risk of end pane blowout? What are your thoughts on this concept? I'd like to see more pics of that end of the tank, as I can't quite make out what's going on with the front to back Eurobrace on that end of tank?

    Thanks!

    That's all the pictures I got. The eurobracing is crisscrossed in the corners to create a nice strong rectangle with double 1/2" thick glass. That makes the eurobrace 1" thick. The external box holds about 1.5g of water since it will run at about 60" around the Durso standpipes. Under the box is a flat piece of acrylic to help support it.

    With the last tank the box wasn't coming off, and I highly doubt it really could if it is bonded properly with new clean surfaces. The end panel of the old tank wasn't blowing out and it was 1/2" thick. This time it is 3/4" thick and the external overflow's bottom panel acts like a cross brace to keep that pane totally straight, 8" down from the top of the tank.

    Your tank is engineered well. Wasn't referring to your tank blowing out, only in general with the tanks short end pane on overflow side not having Eurobrace attached. My question is to the effect if I want to extend the long Eurobrace pieces to the outside edge of overflow box, thus having silicone on top of box as well supporting from above. I want to do this, but wonder if the concern is that if some crashes on overflow box it could fracture Eurobrace and front and/or back tank panes? I need to talk with some tank manufacturers. Thanks, good luck with "the beast" ...

    If you want to support your external overflow with steel, it may be better than adding floating eurobrace to help lift it up. Gravity will always tug at the overflow and the water weight within. I doubt this box needs additional support, but I did talk to a welder about possibly adding some legs bolted into the stand if the need seemed prudent.

    That is great news Marc i have been wondering where you were at on the 400gal thanks for the update.

    PS speaking of MACNA by any chance might you be able to give us a line on where it will be for 2014?

    I only update when I have something to share.

    The next MACNA location will be revealed in exactly one week.
