I would do away with the internal overflow and go external.
Dremel the back of the tank for the overflow, then build an external overflow out of glass and silicone to back wall of tank. yeeeaaaaahh!
If not, your plans look good.
Although external overflow is a great idea to save some room inside the tank, my plans are to have the tank up against the wall. It will be beside the couch at eye-line for viewing while sitting, with a cold beer or two.
Here are some of my inspirations for this buildChris George's Silverstrand ReefAJ_Tsin's 47g Shallow RimlessNeto's DIY 20g ShallowMarlon's Nano Project, 24"x24"x12"
I have to get the tank custom built and I'm in the quoting process. Most likely it will have 3 panes of starphire glass. I need to provide the builder with proper dimensions and measurements for drilling the bottom. Do you think 1 1/8" spaces between the drain holes and return holes are enough for the flanges not to touch?
Standard threaded bulkheads, double threaded or slip? hmmm
