For the frame I used 2x6 and 2x4.
There will be a 75 sump that slides in from the side. The tank is 24x48 and the sump is 18x48 so I wanted to beef up the stand with the 2x6 and make sure all the joints were supporting. Then I clad the whole stand in 1/2" ply to give it more rigidity.
It's solid and probably overkill but I needed piece of mind.
I also made it high so people won't have to bend over to see the tank.
Thanks, this tank is on the edge of what two people can possibly lift alone. LOL found that out getting it in and out of my car.
That is my first concern when I water test this design.
I will be running the returns into the DT very close to the surface so I'm not expecting too much backflow. I also use an ATO so I will be running this section low.
I figure I have 6+ inches of vertical capacity in that section and it's larger than it appears. It will then spill into the skimmer section.
If I need I can encroach into the reserve section which is the rectangular section at top center left.
Hopefully the design holds water though.
Hopefully I can get more work on it tomorrow and post some more pictures.
Not all the glass goes all the way to the top. Not sure what tou meant by ballasts.
