So this build was 100% inspired and modeled from the DIY King, I get tons of info from him. I did things differently in some ways and in others I copied him exactly. I also got TONS of info from guys hear and old build threads. I used MAX ACR to seal the Inside. Dimensions are 8' wide 3' deep 30" tall. Let me start posting some pics.

The stand was built in 2 parts. I needed to be able to get this threw a 30" doorway - so that took a little extra work .

You get to see a pic of my Beautiful helper - wife decided she wanted to do some polishing =). I installed a 3D foam background from universal rocks! I like these foam backgrounds cause you can buy in pieces then cut the to fit! I Hide the heaters in the corner with the water intake pipes / fittings.

Let me know if you guys got any questions - I will be happy to pass on any Info I can =)
 
You said your made changes to what dyi king. What changes did you make. Also what thickness of glass did you go for?

If you don't mind me asking what was you final cost for tank and stand minus the background and filtration. Curious if the extra glass and woodwork made this expensive.

I used 1/2" thick glass, got it from two broken 240G that I bought to fix, which I then broke again trying to move it solo ... lol, Total about $300 in those tanks so u could say that's what I paid for the glass I guess?

As for what I did differently, i used Max ACR not Pond Armor but I did use fiberglass in the corners. I did not make a frame for the glass to sit in after I made the tank, I cut one window out of the plywood larger than the other then used that lip to set the glass into. I also used slightly smaller ledges to set the glass into - not sure But If Joey left a 2" lip to set his glass into all the way around, i only did a 1.6" lip. I did that to give more viewing area and to try and clean it up a bit. Also dident want a Huge plywood lip at the bottom so I kept those areas of wood to a minimum. I used many more screws than he did and as u can see I drew grids to keep everything evenly spaced! I installed side viewing panels and he did not. I think most everything else was done same as he did.

As for what It cost, easier to say what materials I used lol, kinda lost track. Not counting the filters or pluming, Not counting the 3 Glass tri-fold lids which were $200 easy, and Not counting background.

got plywood on sale, Birch Finish grade - 6 sheets = $225
Used Tanks for Glass - $300
Pile of screws $100 easy
2 bottles of wood glue $20?
Max ACR and color tint $200 ish
Brushes, rollers, pans, scale and whatever for Max Acr $100 ?
Fiberglass for corners $30?
Craig jig, screws and wood Plugs $100 or so
7 or 8 tubes of silicone $60 ish

Also spent an easy $275 on molding for the tank and stand (stand prices are not included)
Paint & primer was another $125 (Sherwin Williams marine)

Prices are as close as I can remember - But you can at least get the Idea.

I also noticed that you did not do external bracing unless you count the molding. Not sure if that’s good or bad.
