Very little work today. I am clamping a portion of the overflow and letting the weld-on 16 dry until tomorrow after work. I did finish cutting out the slot. Not perfect, still a bit of clean up left. But after that is finished, I'll scrub the tank out and remove all the debris.
I decided to show some of my Google Sketch Up drawings I had made. Initially I had planned to drill the side with an internal overflow box. But it would either have to be extremely low or extremely deep to work in due to the 4" side brace there.
So I changed it up and made it an external overflow.
It is just a 2x6 stand that is missing quite a bit of the support. I will have a diagonal support as well for a tank this size.
I'll make a 2x4 stand for the 75g sump most likely.
The plan is to use some 45* elbows and not use 90* elbows at all. The baffles are just a brain storm. They will be 1/8" panes most likely. The plan isn't set in stone, but I'll be using foam as a mechanical filter and then some porous rocks for mechanical followed by a heating chamber and then the majority of the sump will be for the return pump and evaporation.
The return will go a long way, but I plan on using a larger than necessary return pump. Horizontal runs don't really detract from flow very much. I'll try and maximize tubing in the return as well. I'll likely make my own spray bar and do more experimenting with slots.
I added something similar to the initial drawing I had found in terms of the stand finish. I am planning on using spiral CFL bulbs but may opt for a lower powered LED and a shallower hood. I have a 24/7 I am going to use as well, primarily for the sunrise and sunset.
And the rear will be largely left open because it will be in a corner. Not sure how I'll do the framing yet, but I'm still brainstorming. The stand will be wrapped in 3/4" birch plywood most likely, since it is fairly cheap. I'll stain it to some what match the furniture in the kitchen/dining room/living room where it will be located.
