If you want to add an emergency overflow you can drill a hole into the side of your overflow box that is higher than the top of your main standpipe. Then run that emergency line on the outside of the tank and down to the sump.

I noticed this too! Your tank WILL overflow at some point if you use the current design. Kien has suggested a good way to fix the problem. Also you mention a "one way flap valve". I'm assuming this is a check valve. If it is, it won't work for very long. Once the tank has been running for a little while there will be some buildup in the pipes which is normal. This buildup will cause the valve to not work simply from preventing a perfect seal or even from preventing the valve from moving at all.

Btw, your tank is a 33 not a 33 long. A 33 long is 48" long, yours appears to be the standard 36" long.

It is a great looking tank though, and I am interested to see how it turns out!
