Exactly, the rule of any liquid syphon is that if theres a air break in it, itll stop. So yes by carefully positioning BOTH the overflow and returns properly, youll avoid a huge drop flow to your sump

What u basically have to do is play around alot to get it all perfect. One of the reasons I could sleep the first night

If you do a good job with ur siphon break and have the plumbing just right, having 4" of back-flow room should be good. Maybe I'm just the paranoid kind that likes a bit more just in case.

is there such a thing a too much overflow? like between these two overflow boxes, one is rated at 600 gph and the other is rated at 800 gph. both have a lift pump to maintain a good siphon. if i have a return pump that is rated at 800 gph at 4' and i t into the return line to feed my refugium, there by reducing the flow back to the tank would i be worse off having the 800gph overflow?

Nope you should be ok. The overflows will only "overflow" the same amount of water that your return pump pushes back into the tank. Npw when your return pump pushes more than your overflow can handle, thats a problem

yep, im subscribed to your 125 build. shame for me but good that both you and carey are at the point of stocking. im stuck thinking about mechanics behind it all and you guy are learning live stock.... oh well at least the info will be there when i get that far. although ill probably enlist carey's build because hers is less predator. your fish are amazing btw.
