Need to ID my new tank size

[DonMorse]

I hope this isn't a repost, I couldn't find where I posted before.

I just got a "new" (to me anyway) tank. It is 72x20x19 does anyone have an accurate idea of the size? I'm guessing about 125 gal.
Also this is just a tank so I'll be building it up from scratch. It has a small crack on the bottom but I've sealed these before (never on so large a tank though) and I'll be building a stand, hood, cover etc. I plan to use my 31 gal as a displayed refugium. Any tips or advice is welcome, you've been great help in the past. Thanks -Don

i think it is more like a 150 gal i have a 120 48x24x24

sounds like a 125, but it is a little different than mine. mine is 72X18X22.

close Don, to calculate the actual volume of a cube, take the length times the width times the height and divide the product by 231 to solve for volume in gallons from inch measurements:

72 x 20 x 19 = 27360 divided by 231 = 118.4 gal. (US)

To get actual volume, always use the internal measurements of the tank, but as a rule of thumb to convey a size in gallons, most folks just use the external measurements to indicate a size of tank.

That crack would make me very uncomfortable with that much water pushing on it. How are you going to seal it?

Tom, thanks for that formula I guess in the interest of round numbers the LFS would call it a 120 for hood purposes etc.

Well motorslave; I'm planning on using GE Silicone II. I've used it in the past. The crack is razor thin and no glass is missing. I'm hoping the pressure is enough to bind it in the crack and not allow any water around it. I'll use a wider patch area around the crack. Of coure it will get filled and left for a couple days before I try to use it.

Any one have any advice or cautions? I've been at this for just about a year and a half and I'm learning every day.

THE TANK IS CRACKED???!?!!!


I see the purchase of a large wet/dry vacuum in your future...


For what it would cost to get a new tank Vs. what it will cost to clean up the seawater and sand, replace the specimens you lose, and the time to get things going again WHEN the take breaks (notice I didn't say "IF"...), you would be smart to go ahead and replace the tank now or replace at least the cracked pane.

Heck, there are lots of empty 125 gal 6' tanks out there, I have one sitting in the carport right now waiting for a good project. Check the local paters for a used tank (or the classifieds at any number of regional marine aquaria sites)

Once a tank cracks, it is just a matter of time before the crack goes to a break, and trying to explain to a SO why you put water back into such a tank on the hardwood will test even the most ardent attorney's skills at the use of smoke and mirrors..

I had a 29 gallon FW that had a tiny chip on the outside corner. Seemed like no big deal, it wasn't even a crack. That was until my son woke me at 3:00 AM when the tank collapsed. I definately would NOT take the chance with 1000 pounds of water. Just my opinion.

To figure out size multiply the 3 numbers and divide by 231. Approximately 120 gallons. HTH
