View Full Version : The making of an External Overflow
02/03/2006, 04:00 PM
I have a 125 Gal I got used it had twin overflows I am going to take out the internal overflows and do one external on the back .
Here are the pic of the overflow before
More will follow as Steve and I cut the back and make the overflow box

cool. where are you putting this tank? Is it going in the wall where you had that other empty tank when I was there like a year ago?
Sounds like another good thread. I'm going to search for that link I was talking about at my house. The guy that created the overflow on the end and put the Tunze's behind the glass. It's very cool.
Here is the Thread, It's not the greatest thread for info, but this one picture really shows the unique design. Water flows through the eggcrate to feed the Tunze's, the overflow part is the center piece.
If it's possible, see if you can take a short movie of the Glass being cut, or ground, however you do it. I'd like to see that. I just bought a dremel and the Tile bit that Steve recommended.

Steve has taken movies, I think I've seen them. I could be mistaken.

(sorry for thread hijack) I just drilled my 29 gallon a couple of days ago with a roto zip and a tile cutting bit. It was super easy to do was so suprized how it worked. I am now a beliver that you can drill glass with out any bad effects.
So how long for the actual cutting? Looks like it's over 12" long, how long is it.
Looks like a nice job so far. I will never buy another tank with an overflow, just buy Steve a couple beers and look what you get:)

It took longer to setup than it did to do the cutting
At the most 10 min
It is 16 1/2 long
It cost me Coffee ,Cinnamon Raisn Bagel and a Sausage and Cheese Omelette
Here are the old holes after removing the overflow boxes
I just cut some glass and silicone them in place
Here is the overflow box silicone waiting to dry
Almost time to have a beer:D

Great Video Steve
The guy taking it needs to drink less coffee:D
Hey, good video of an Arm there. Really, it's a good video. You move pretty quick. I'm guessing you can see where you are cutting better than the video can. You really Flood the thing dont you?
So, how does the bit hold up? Is it spent after one cut like that, or was that an older bit already?
Nice. Thanks for the rockumentary.
Rotozip? or Dremel? Drill? Anything special about the bit itself? What did you mark the original line with? What is the dam built with?
Thanks for posting the info, progress and video!
How many passes on the cut line do you make scoring it before you attempt the cut? Once you break through do you feed additional water? Is this gravity fed? Is that what the airline tube was for?

very cool. If I ever have a glass tank I'll definitely be doing that!
so the overflow box is just siliconed together and then siliconed onto the back of the tank? does it need any other support or framing? pretty amazing what silicone can hold together.

Im glad u all like it, Jason u where shaking cuz u wanted a beer.
Hef after u score the glass its easy to just follow ur line & the bit is good for how ever many more u can cut, most of the time they brake on me & thats it :)
Phly i did 2 passes on the scoring,once i broke through the water kept flowing on an angle ( i wont say the floor was?) the airline was the RO water line & water just kept flowing out ( nothing like pure di water to make ur cut )
it was a rotozip with a tile bit that they sell for the rotozip.
the silicone is stronger then we all think the glass box will brake before the ssilicone gives, u dont need any support.
