rogergolf66 - emergency overflow is when you put a bulkhead very high in your tank. You plump this to either a drain, outside etc. So, if my tank starts filling above it's "Normal" level and is about to spill over onto the floor - it instead flows into the "emergency overflow" and down the drain/outside etc. It's a lot more work, but worth it IMO. I've added this to my Sump, Refugium, and my Grasses tank. Any tank that receives water from other tanks - got it added. I have a lot of tanks and a lot of water flowing, I don't want 500 - 600 gallons of water on my floor!
On a side note - doing this made my plumbing for my water change easier. I just plumbed all the tanks for water change into my emergency overflow plumbing. I'll be filling my sump with water and that will be my main water change area. This is tee'd off one of my pumps so changing 50g of water will take seconds. Also I added my QT into the "Change water" plumbing. I just drilled a hole a few inches from the bottom and plumbed it into my emergency overflow plumbing. This way I can change the water in the QT just by turning a ball valve. This will also come in handy when I need to clean the QT - that is the reason I put the hole so low in the tank.
I hope this helps - I'll be making one of my drawings a little later once things settle down. BTW - you need to make sure your flow is correct, otherwise you my be changing your water into another tank, or your emergency overflow is more of an emergency. For the first time in my life I'm glad I had to take fluid mechanics as part of my engineering studies
