Over the last few weeks I spent more time researching silicone joining methods and understanding tank building a lot more. I made some updates after fully realizing how insane this build is. If I could do it all over I would reduce the height and make it 24" high instead of 30". Those extra 6" are what might keep me up at night once I get water in it in two weeks.
With that said I am adding some updates to try any make everything a bit more secure. This has defiantly been a fun experiment in tank building and I am happy where where it is so far.
So here is what I got done so far...
I blew out a space behind the wall so that I can do my plumbing. I am setting up the sump in the boiler room. (My other crazy idea is the water heaters and furnace might help to heat my tank lol)
I decided to add two 1/2" bottom panes (total of 1" of glass on the bottom) with the seams staggered and the glass layers siliconed together. This should eliminate or reduce any horizontal tension on either seam created by the weight of the water.
The column is covered in 1/2" glass as well so that no water will hit the pole. I will add a cap at the top of the column so that so water can enter from the top as well.
I then drilled the back pane of glass for the ghost overflow ( I felt like I was getting ahead of myself because I don't even know if this all will hold water lol)
Finally I got all the sides of the tank up. It was super heavy to lift and very scary to make sure it was secure.
Now I am at the point of cleaning out the seams so I can:
add the Euro Bracing on the bottom like Born Handy Recommended,
add panes of glass over the seams where the bottom sheet joins,
add Euro Bracing on the top,
and finally add 2 horizontal 4" braces on the top on either side of the pole.
It takes for ever to get the excess silicone all cleaned from the glass and now I am realizing why a 30" high tank is so much more work!
I am also looking into corner caps for the front of the tank. I see people use plastic caps, but I am considering using two thin pieces of 1/4" to cap the corners. I haven't seen anyone use glass caps before, but my thinking is that it will add more structural support and the glass will bond to the glass better than plastic. Am I wrong in my line of thinking?
Thanks again for all the feedback thus far and joining me on this crazy project. This forum has been my place to look to as my girlfriend is tired of me talking her ear off about fish, corals, glass and silicone.
