Internal Overflow Box

Don't believe there is any such thing. The internal overflow box is prefabed into predrilled aquariums ~ you have to buy the whole tank or make it yourself. The external overflow hangs on the back of your aquarium and hoses run to a sump beneath your tank. Or are you talking about just the inside portion of the overflow box?

If your going to drill your tank, you can just use a pvc elbow from your bulkhead pointed toward the top of the tank. the water flows over the top of the elbow and down to the sump, by adjusting the angle of the elbow, you raise or lower the water level in your DT. When the water level gets too low in your DT it stops draining. If you try to use a overflow box, you'll have to drill that also and somehow seal it to your tank.

I thought with the overflow box (on the inside) you just drill one or two holes on the bottom and glue the overflow wall to the bottom and the sides, etc......

You can't drill the bottom of your tank! The bottom of aqariums are always tempered glass, and trying to drill them results in shattered tank
. Thats why we said to drill your holes in the back wall of the tank.

yeah i wondered. But i have seen some tanks at the lfs that are drilled in the bottom, but they are different glass. Alrighty so i drill a hole or two in the bottom back behind my overflow wall. Then put the then put the strainers and plumbing in. Is there a drawing or picture of the 90 degree way that was suggested earlier?

You don't want to drill at the bottom of the back wall, unless you use the overflow, and then only if you are absolutely sure that you have everything sealed. Otherwise, nice big puddle on the floor = no water in the tank!
I don't have any pictures of the 90, but could get you some ~ it'll take a couple of days. If you use the elbow, you want to drill the drain hole (about 1 1/2 diameter) about 4 or 5 inches from the edge and 3 or 4 inches below the plastic lip ~ seal hole with an appropriately sized bulkhead fitting, and and plumb as required. The size of your return hose will determine the size of your return hole (also requires a bulkhead). Also, if you've never drilled glass, you may want to consider allowing your local glass shop to do the drilling for you, less chance of breakage.

where did you drill, and where did you order it all from?

personally, I think you will save a ton of money if you only drill one hole and use some pvc pipe to create your overflow. If you need a diagram, I will post one...
The benefit to the pipe, other then the money is quick water changes, just like scopus tang said. If you don't like the look of the pvc in your aquarium, you can always cover it up with rocks or even glue zoanthids on it and they will take it over.

I have a six 30 gallon tanks with two holes drilled on the back wall of the tank. I do not suggest drilling the bottom of the glass. Usually and almost all glass aquariums have tempered bottoms.

yes i would love a diagram. Ok to better under stand this. There is an 90 degree pvc elbow pointing up towards the lights. and the water flows over the hole and down through the back of the tank. The placement of the pipe is in the top of the tank on the back glass. Shouldnt there be something over the hole some things dont go over and down the pipe?

Yes, a simple sponge prefilter will work, or sometype of nylon netting zip tied over the hole.

just for the record my over flow boxes are drilled through the bottom of my tank my sides are glass so I am assuming so is the bottom

Yes, but did you drill them or did they come predrilled? My predrilled tank is also drilled through the bottom, but I haven't talked to a glass shop yet that is willing to attempt drilling tempered glass. Obviously it can be done, but it requires a little different/more difficult process?!

My friend you are absolutely correct my tank was pre-drilled I have drilled through glass using a special abrasive material and special drill bit but only a small diameter hole at the expenses of loosing two pieces until I was successful it was not on a tank. And again I will agree this is something not to be tried on a tank
