Notching glass for external overflow

[mark]

^ any idea the price?

[Spyd]

It's not cheap. Somehwere around $200 US is what I have read. It is made by reefsavvy. You would have to email them and find out. I believe it comes with all bulkheads, etc as well though.

Yes thats the plan. Just your typical external overflow where you have the box mounted externally and a notch or slit cut into the tank to allow the water to flow into the overflow box.

Personally I don't like egg-crate and find it breaks easily and rots away faster over time egg-crate is a brittle plastic and just not my fave thing to work with

Thanks Lockrookie, PM sent!

This is the ghost overflow. I think it is a fantastic idea on only requires holes to be drilled instead of cutting out a section of glass.

Thats a really cool idea, too bad they don't make the external box itself taller. Also the cost itself is well above what it will cost for me to just notch or cut a slit in the glass. Thanks for the link

I like that ghost over flow. Looks pretty sweet and an easy way to add an external overflow onto any tank

rather than notch have seen similar in idea to the Ghost OF (just holes, no notch).

Piece of glass about 5-6" wide, length the same as the tank for a coast to coast lip. Glass is siliconed at an angle, holes drilled through back glass (no bulkheads needed) and external overflow box constructed.

Wouldn't fish/snails and such end up in your overflow box with just holes? I was thinking of that earlier.

I've seen this done before: to cut the notch, you essentially cut two holes as far apart from each other as the length you want the notch to be. Then you use a glass cutter to score the bottom part of one circle to the other, and break away the glass.

using a dremmel sucks the big one, I used a glass cutter then used the dremmel just to smooth out the cut. you need running water to keep it cool, and you very well might destroy your dremmel, or at least the flexable wand part of it

if I had to do it again I would drill two holes one on each end of the cut out, the using a glass cutter scribe to conect them, bust out the glass and smooth it over.

Thanks for the input. That was my plan with drilling the corners of the notch and then using my angle grinder and a diamond cutoff wheel.

Yea I was starting to think that a dremel would not be the best to use and was considering using a rotozip, then I just realised I have a angle grinder and a diamond cutoff wheel. Yes my plan was to do this on my front lawn with the hose running constant water over it.

Check out this guy using his dremel wand/flexible shaft underwater to do some fragging....
