Drilled or overflow box
Just wondering if their is a real difference between having your tank drilled or having an overflow box. Can someone tell me which is better or if their is a real difference or not? I have a glass 55 gallon but am still researching this question before I set it up?
So far I'm getting no real conclusive answer. Is it a prefference thing or is there some advantages one way or the other??? Any thoughts would be great!!!!!! |

There are some HOB overflows (Lifereef and Amiracle) that are really good, but drilled overflows are more or less bulletproof. I'd say drill it while you still can, there's no more frequent regret you hear than deciding not to drill.

Go drilled....the only issue I ever have with my reef tank is the overflow breaking syphon. It's better now with my CPR and airlifter pump but it still worry's me when I travel.
I'm setting up a new tank soon and it will be drilled. -Salty |

Drilled takes out the "what if". What if my pump fails, what if my siphon breaks... etc.
If the tank is glass, you may not be able to drill it w/o cracking. Usually it is only recommended to drill acrylic DIY. Pre-drilled from manufacturer is the only drilling I have heard complaints about, lots of times the one overflow compartment is not really sufficient for the size of tank. We have a 72 bow that is not drilled, and a 90 drilled by the manufacturer. Next time, I am saving my money for the custom drilled acryllic! For now, both you and I are probably stuck with the overflow boxes.

A good quality, properly set up U tube system will never break siphon. It should run indefinitely. If that 55 has a tempered bottom you would have to drill through the back which is a good way to do it anyway.

I have an AG megaflow 65 and am about to update to something larger and am strongly considering something else besides the AG. their overflow boxes are difficult to aquascape around, I place no value in the part of their megaflows which pull water in from any level except the top - they look like hell, bulkheads scare me almost as much as overflow tubles.
So I am thinking of going back to a quality overflow box - with little switch which senses too high a level in the main tank that shuts off the main pump

I personally hate the look of the top to bottom overflows in a RR tank. The corner ones are not bad though. I'd go that way for RR. Rear drilled is better. The nicest is having slots cut in the glass with an external overflow. No inside box or plumbing at all. A problem in the bottom of a drilled tank has the potential to empty the entire contents of a tank. At least a HOB will never do that. A quality U Tube overflow is much more reliable than most people realize. Cr@ppy products like CPR have given HOB a bad rap.

No reason not to have peace of mind with a good U Tube overflow setup. My setup is 100% reliable. People have run years without issue (a friend mine is going on 6 years). I dont worry about it one bit. The only possible way for mine to break siphon is to physically remove the U Tubes from the system.

I agree so far except that a megaflow will only empty the contents of the box not the whole reef or anywhere near it.

I'd go for the drilled tank. I bought a bit to drill my new 150 but I need a bigger one. I'm doing (2) 1.5" drains in the back once I buy the new bit. Anyone need a bit for 1" plumbing? Mine has only three 1/4" practice holes of use on it. It's seems a little intimidating at first but if you have any mechanical ability it shouldn't be a problem. Just gotta go slow and keep the bit wet and cold....

jnick, on my practice trys I was completely successfull. That immediately gave me the confidence to actually drill my tank. I just went real slow. Seriously the only pressure on the bit was the weight of the drill. You could probably put a little pressure but I didn't want to risk it. I wasn't in a hurry.
The Twin-Flo's are still available. Most pet stores will say they aren't from my experience. I even called All Glass and they said the old style wasn't available. Finally I got a LFS to say yes they are available but it would be special order and take some time. Last edited by GoldStripe; 03/24/2005 at 03:10 PM. |

I still don't like them enough - I like them more than megaflow
What I really want apparently is an offsize - 48 by 25 deep by 18 Quote:
