cutting tank

carnut · #1 12-07-2014, 10:56 PM

Has anyone ever tried cutting a tank in half. I have one I like the length and width but not the height. Would like to cut it in half to get the height I want.

Thanks

I cut the side of my tank off for an external overflow. I'd say it's certainly not for the faint of heart, that's for sure.
You're probably far, far better off just purchasing the size tank you want.

Thickness of the glass will determine whether it's feasible or not I reckon. Also need to confirm that the sides you wish to cut are not tempered. I've been contemplating giving this a go as well. I wouldn't risk it with a larger display tank, but my current 77 gal Hagen display will probably become a sump or 'fuge when I finally upgrade to a larger set up. Something shorter than 24" is what I'd prefer & the 77 gallon will be a good candidate since I know it's not tempered & it's getting a few scratches on it after many years duty as a display. I have a small wet tile saw & think that if I take it slow & have a few spare blades on hand, should be able to pull it off. Will be awkward & heavy, but worth a try. If it breaks no biggy. If it works, I have a great sump. The new display will probably be a custom build though.

Score it first if your going to attempt to cut it in this manner. Risky venture! Good luck : )

Really sounds like a disaster waiting to happen. JMO. Good luck.

The way things are going at the moment, it will be quite a while until I'm ready for the planned upgrade, so won't be any cutting in the near future. I like to keep tabs on threads like this to see what folks' experiences with cutting tanks/glass are. The old 77 will have to do as a display until I finish all the renos on my even older house.....

I assume scoring the glass will minimize the chance of the thing shattering as I push it along into the blade? What do I score it with, a glass cutter? I've never been any good at that!

When professional glass cutters do it, they score and snap a flat piece of glass. They would probably never even attempt to cut an aquarium that is still intact.

Well, I'm not a professional (glass cutter that is) & am not dealing with a flat piece of glass. Neither is the OP. Maybe in a year or so, I'll give it a go & report back. In the meantime it would be great if someone that's actually tried this would chime in.

I have cut down three tanks for use in sump, ato and frag tank. I did however use a simple glass cutter, snap into tank pane by pane after cutting silicone out to cut height.

Cutting with a wet saw will most certainly cut glass. However by hand on a four foot long pane you will probably get 75-90% of the way through then it will most likely break. Why I suggested scoring it prior. An initial score may keep a break controlled. It may not. But for a sump to reuse a tank you already have, sure give it a shot if you want. I can't promise you won't break it, and a good chance you will but it's your tank, have fun with it if you want. Even a grinder with a dry diamond blade can cut a tank in half. Just play safe. I'm sure I don't need to tell you glass is sharp.

Just don't try it on a tank you don't want to loose. OP!
