I've used a HOB overflow for 7 yrs and never had a incident (knock on wood) but see why other don't like them.
What kind do you use/whats your set up?

Thanks, and as far as "ghetto" set ups go...if it ain't broken don't bother fixing it! It clearly works and that's all that mattersNot sure, it's so old. It's just your average clear overflow with a black skimmer box.
My Setup is 55 gallon Tank,
Sump
Mag 12 return pump valved down to about 500 gph.
Basic protein skimmer rated for 75 gallons.
4X54watt T5 lights with led moons.
Homemade HOB Refugium w/ Chaeto algae, 26 watt compact florescent bulb.
I consider my setup as very "Getto" or DIY . haven't bought equipment in many yrs.
Except testing supplies and salt mix and lights.

With regards to hang on back overflows, I have used a few sizes of the CPR wide overflows (versus ones that use inverted U tubes) with good success:

The trick with these is that they will slowly accumulate air at the top of the chamber. Some (mainly commercial) websites recommend using a Toms Aqualifter pump to clear this, but in all honesty I can't recommend this. The pump gets clogged too quickly, even with their sponge attachment, and then air can build up. Instead I use a normal Maxijet 1200 powerhead with traditional airline tubing running from the powerhead to the outlet on the overflow box. Now the airline will slowly accumulate algae and debris in it thus decreasing the air throughput (just replace the tubing every now and then), and of course you have to make sure the powerhead stays in good, clean operating shape. But this is much more reliable than using a small airlifter pump.
I would still agree with others that if you can start with a drilled tank you will be happier, but if you must use a non-drilled tank, and it is either tempered glass (can't be drilled) or you aren't comfortable or can't find somebody to drill it for you, this overflow solution will work. (And it allows a LOT more water throughput than the inverted U tubes).
