HOB overflows

U-tube overflows work great. The "siphon-wall" or wier style overflows are prone to fail because the water does not move through the siphon path fast enough.
I have had no problems and no air trapped in my u-tube overflow. The other styles require a powerhead or pump to keep air out of the siphon. It is just a flood waiting to happen

i would also encourage drilling the tank. i have an overflow box that works ok, but i still have some problems with air getting trapped in the U tube. seems that when i first start the siphon, there are air bubbles that come from the overflow and as they move through the tube, some of them stick to the walls and inevitably catch other bubbles with build into a large bubble that restricts the flow of water. it doesn't stop it, but does slow it down. in addition, by drilling, you can establish the amount of flow you want to have instead of relying on the gph rating of the overflow.

Hey...I am glad you asked this question. I will be setting up my 180 gal. once I move around the first of the year and was wondering how to do something like this without having to drill my tank.
I am also glad to know that there will be some fellow reefers nearby once I move. (I will be moving to Hamlin).
Are there any good LFS's in Abilene?

I'm using the CPR that others complain about. I've had no problems with it, but really have little to compare it too. It works fine. The pump keeps the siphon from breaking. The flow rate through a u-tube does the same thing. The problem that u-tubes have is that when algae builds up in them, the flow rate is diminished, while the velocity of the water increases. If you keep them clean, they're ideal. If you let them go... it can end up flooding your living room.
I'm really with the "get it drilled" crowd. $100 or so on an overflow box, or $25 a hole... that works better... and is quieter... get it drilled.

FavaBean, yes...that big huge city of Hamlin. 
That is good that there is at least one place to go. Most likely will purchase everything online though if not a good selection.
Well, right now hubby and I work at a boat dealership here in So. Padre.
We bought a house and closed on July 10...3 days later Advanced Outdoors (boat manufacturer) suffered a fire; which is where hubby will work. I may work there if he doesn't hire someone to do that job before hand.
We are actually going to be in Hamlin working on the house this weekend trying to get it ready for us to move into at the beginning of the year.
I bought my 180 gallon acrylic right after Christmas last year and then we decided we wanted to go help Joel at Advanced Outdoors (he is a great guy), so my tank is still wrapped up on the pallet it was shipped on. I haven't even looked at it out of the box yet. Talk about being patient...I want nothing more than to get going, but do not want to have to move any inhabitants 10 hours away. I will already have to move a 55 gallon freshwater.
Okay, sorry to be off topic... now back to our regularly scheduled topic.
I do not wish to drill my acrylic tank for warranty reasons, so a HOB overflow will work if I choose to add a sump (I am still undecided on this). I am just absolutely no good at figuring out plumbing. I am trying to purchase all or at least most of the equipment before the move.

Thank you
Thank you
Wow the amount of responses you get here is amazing. Can all tanks be drilled if so Ill be looking for a place to get it done. I really wanted to get a drilled tank but I couldnt pass up the deal on this one.
As for abilene I am pretty new here just a couple of months but there are the two LFS. The one as was mentioned probably could use some cleaning up to put it lightly, the fish kind of looked poor. as for the other store I think the owner there likes what he likes and and doesnt want to talk about anything else. but when you know what your doing I guess you have that right. ill still take my business to him rather than the other.
Please let me know if there are certain tanks that cannot be drilled! Thanks Agian
For those of you in abilene do you have pictures of your tanks?
