OK, my 40b is online, pretty much done, with coral in it.
This is my shortened version of that build- still pretty long though;
This was the 40B, drilled in the bottom near the corners for 1" bulkheads when I got it.
I used it for one of the holding tanks for my 125-180 transfer June 2014.
I've kept it upside down so dust wouldnt settle in it much:
I moved my 55g I used as a mixing container out from under the stairs where it's been since June, so I could use the space under the frag tank and get in and out of there easy:
After much thought on sound stand building principles, yet leaving the area open under the tank to get it there and also use it as storage area, I decided on a design trhat incorporated the existing walls and I build a frame for the bottom of the tank- that sits on the braced area attached to the walls:
In using sound principles- all four corners are directly loaded into an upright 2x4.
These 4 uprights are attached to the existing walls- so no racking/leaning/failure.
Based on my planning/estimates of space/height- I had to notch out the stairwell supports just a bit:
I had recently added my Marineland 5500 RP into my system to my 180-with a bypass that was eventually used to supply the 40b frag tank:
Here's the FT in it's spot- up higher than my sump- which is pretty high up to lessen head height to the DT upstairs.
