does any one have external overflow that works good? what happens when the power goes out and then comes back on after you lose suction. does the tank over flow? thanks

They can work great. However their are a few design flaws compared to internal overflows. For one, if the filter on the overflow plugs up... your entire sump will be pumped into your main display. Don't ask how I have first hand experience in that. Lets just say.. don't add filter floss to the overflow box!
Most will maintain their siphon in the even the power goes out. I never had a problem with that. Some models, particularly the cpr over flows have an automatic restart siphon that you can connect to a powerhead.

CPR's are the best, why you ask
1. They are quiet.
2. They move a lot of water
3. They have a
[hr]
on top to attach to a powerhead to draw air out of the siphon tube. (this starts them back up after a power outage)
4. We've lost power quite a few times and I've never had any problems with it starting back up.

What kind of problems did you have with the cpr's?

One thing was the
[hr]
kept clogging up so it would lose the siphon. The really strange thing was on both of the ones I had over time I just couldn't keep the air out of the siphon chamber. I had maxi power heads(the big one, I can't remember the model) on them. I guess the main issue is I always had to mess with them which made the a reliability issue to me. The lifereefs have never in over two years lost a syphon on me. The maintenance on them is cleaning the U tube every month or so. Tony, you know how it is. Everyone has good and bad experiences which form their opinions on equipment. I'm sure the cpr's are fine, I just had bad experiences with them. And again I think I have a couple laying around if anyone wants them. By the way have I been reading you have some new critters, you know the rules Picture, pictures pictures.:happy:

Lifereef here - has not failed me once.
Providing you have enough flow into the tank from the return pump - enough flow to drive out any small entrapped air bubbles that may want to accumulate in the upper curve of the U tube - most well designed external overflows are very reliable. Most.
The only way I can see my Lifereef unit to fail - would be to not have sufficient flow through it.
Maintaining prefilters and such goes without question.
