DIY Glass sump assembled and water tested.
This is the biggest tank I have made so far myself and so far it looks good with no leaks or bowing.
Sump holds around 120G (440L) of water
60x26x18" (150x65x45cm)
Sump will handle around 40G (150 L) of water backflowing when return pumps are shut down which should accomodate the volume drained from tank and fishroom.
skimmers partition is 16x26x10" (40x65x25cm) then a 18G (65 L) Return partition and a couple 16G 60L partitions 12x26x12" (30x65x30cm) partitions which will act as Fuges and might be converted into inline frag tanks when the Fishroom in functional.

    Looks great! I'm impressed that their is no bowing. What type of silicon sealant are you using and where did you get it from? I'm also curious about how much did something like this set you back because I would love to venture into making my own custom cube as my next project. Keep up the good work!

    Thanks,
    Used Den Braven Aquarium Silicon.
    Its a very good quality silicon Made in Holland. I guess the baffles and separations somehow act like braces and prevent bowing. Used 10 mm glass on this one Cost of glass and Silicon didn't exceed 150 usd. Initial plan was to add some Eurobracing on it to prevent bowing and make it stronger especially whenthe pumps are turned off and the sump fills up. didn't want to place those before hand to allow for easy equipment positioning and not have braces interfeering with anything. Still with how large the sump is I'm reconsidering that and might just go ahead and install some braces. My Current Sump for my 150g was built by a tank builder it is a bit smaller than this one :
    44"x20x20 Vs the Current 60x 26x18 and it has roughly the same design except that this one have the additional fuge partition and he didn't install any bracing and it's been running since 3-4 years....
    any thoughts on this?

    Another silicone that is often highly recommended is Momentive RTV 108 or RTV 103. The "8" and the "3" refer to the color. One is black and one is clear; I can't remember which off the top of my head. When GE made this (before Momentive bought the "recipe" it was labeled "aquarium safe." Momentive no longer certifies it for this use, but make a quick call to Momentive and they will tell you the product is exactly the same as when GE made it. It's FDA and U.S. Military approved for food safe storage. It's also rated as a sealant AND as an adhesive. Most silicone is NOT adhesive so that's something to consider. Anyway, that's what I recently redid a tank and sump with and the stuff works great. To be fair, I have not had any fish or coral in those tanks since redoing them, but a quick check over at reefcentral.com will assure you that many find use of any other silicone to be all but blasphemy. It's a bit more expensive ($15 from McMaster.com as opposed to $5 for GE I/II at Lowes), but the good mechanical properties you get more than justify the price.

    Thanks for the info, I'm not located in the states and not sure those exist around here...
