Ok, I can now start to see the light at the end of the tunnel.I laid the tank on it's side and now I'm finally done drilling/enlarging all the holes on the bottom. Next step is to assemble the standpipes and place them inside of the overflow. This has to be done prior to putting the tank on the stand because the top of the tank is too close to the ceiling and I won't be able to feed the standpipes through.
Also the darn epoxy didn't cure properly on the foam rock structure that I was making so unfortunately I'm going to have to go without it. That was just a huge waste of time.
There's two holes drilled, one at each end, for the return for the closed loop.

The tree middle holes are for one inch bulkhead fittings for my overflow to the sump and skimmers. The other two holes are for the returns. The hole on the bottom is for a 1 1/2" bulkhead fitting for the closed loop.
