Let me know what you think of my 54 gallon reef

[nlreefguy]

yes, as I see it, the two biggest problems would be:

1. failure of the overflow with the subsequent overflow of the display by the system pump pumping the water out of the sump

2. failure of the system pump with the subsequent overflow of the sump with display tank water

If the sump has large enough void space and float switches are installed on the display to turn off the sytem pump, this should elimiate (or at least reduce the chances of) both possibilities, right?

Oh, the dimensions of the tank are 36X18X20. Thanks for the comments so far! Keep 'em coming!
