I have one of these, and while its sized for 5x7, you'll need the 3.5 
gallon 8x10 tanks to use it. For me, the Morse tank seems to have a lot 
of hoops to jump through just to get daylight developing.  I'd rather 
use the stainless steel racks to hold the neg hangers and stay dark.  
They hold a lot more and are easier to clean.
