cutting a 30 inch tall tank to 24 inches tall.
 

well like the title says I was just wondering if there was anyway to cut my 72 x 30 x 24 inch tank to 72 x 24 x 24?

put in a deep sand bed, say about 6"

There is but it might not be pretty. You could take the whole tank apart and take the glass to a glass shop and have them do it or get a diamond blade for a grinder and diy.

You would have to take it apart and have the glass professionally cut, it'll be too thick for the average DIY to cut a 6" strip 72" long.

Personally I don't think it would be worth the trouble and you'd be better off buying a new tank but that's just what I would do. A standard 180 gallon tank is 6x2x2 and showing up with cash to somewhere like BWA would probably score you a deal if there was a tank in stock ready to go.

Well the tank is my spare its in my parents shed right now. I just really hate the 30 inch deep and the tank bows a bit when full so I dont really want to use it again at 30 inches. At 24 inches there would be alot less head pressure on the glass. I am going to need it in the next month or two to put my fish in while I move and set up my new tank. I think I will try and cut it and put a coast to coast overflow on the back. worst case scenario I break it and need to wait for another used big tank to come up for sale.

Why not just try and dremel an overflow 6" down from the top and toss a box on it? That way you don't need to mess with taking it apart.

I thought about that too becuase it is just a temporary tank I doesnt have to look that good. But if the cutting worked maybe one day I could have 2 big tanks set up. lol

Has anyone tried cutting something that big with a diamond blade? I would use a skil saw and put a 6 foot hand level along the whole thing so I get a straight cut.

Check the beginnings of Dez's thread. He did a lot of this type of dremelling. Heck you could just do a coast-to-coast 6" down and drill regular bulkheads into it. Sounds like you want to not have it look silly as well but a canopy could easily hide a 6" rim.

I would maybe use masking tape to cut down on the shelling
Of the glass. Then maybe use you skill saw idea with lots of water. I just used a regular diamond blade from totem on my grinder.
