Math wiz please.

Good afternoon all,
So I purchased at tank & unsure of the amount of gallons it is. It is a half cylinder, 4'9" along the back, 30" back to front, 28" tall, & made of 1" thick glass. Thanks! -Jon

Just to give you an idea.

You need to give us the inside measurements to be sure, but let's have a go.

To get the volume of a whole cylinder, the formula is:

Volume = pi x radius squared x height

Let's guess you gave us outer dimensions, but you mentioned the glass is 1", so 30 - 1 = 29" - let's say the inner radius is 29". The internal height is 28 - 1 = 27".

V = 3.141593 x ( 29 x 29 ) x 27

V = 3.141593 x 841 x 27

V = 71336 cubic inches = ~308 US gallons

Half of that for a half a cylinder would be ~154 US gallons.

Thank Gawd for the Internet! I would never have been able to figure this stuff out for myself.

I have the same tank it is a 144 gal

Nice looking tank you have there. What are your plans reef, FOWLR?

[jgp]

I thought it was a 144g as well since thats all i seem to see online as a half cylinder. Thank you mr dave for your time & math efforts! I plan on making it a FOWLR tank. but i got a lot of plumbing ahead of me as well as probably going to rebuild the stand with some more promising wood. The current stand has this board similar to particle board but its fraying & when its wet becomes mush. This is a hobby after all, I've spent a year just looking for my fav tank so no rush I suppose. SHIVER, do you have a thread on your build? I'd like to see your set up.

That is a nice looking stand, I would brace the inside with some 2x4s and then seal it with 2 part epoxy and go with it!

[jgp]

floowid, can you pls go into detail on how you'd detail on how you'd exactly save this stand? I'd much rather do this than rebuild it bc from the outside it is beautiful. i've enclosed a few pics to show you what I was talking about. Maybe you may find it's worse than you thought....

Bump (sry)

Anybodys input appreciated!!

Bracing it would be some work, but it is possible. I would start with some 2x2s and make a framework for the top and bottom. Cut a piece of 1/2 inch plywood to overlay the bottom framework so you have a level bottom again, or you could also just forego the bottom framework and use 3/4 ply. I have included a REALLY rough paint drawing to demonstrate it visually. The black outline is your stand. The red lines would be the 2x2 top (and bottom if desired) frameworks. And at the points where I made amorphous yellowish squares is where I would place 2x4 supports. Put some diagonal braces across the back, and some 45 degree braces on the tops of all the 2x4 uprights. If you are still worried structurally, you could double up the 2x4s.

Normally I wouldn't worry about going to such lengths for a stand made of press wood, but it really seems to go with the tank well. Only you can decide if saving it is worth the effort.

You could have used the MIB method of figuring out the water volume.

Fill up a 10 gallon aquarium, dump that water in your tank, measure the water height, measure tank height, divide using your cell phone and then go drink a beer or two.

I hope you can save that stand.

[jgp]

Floowid, thanks a bunch, I'm gonna go with this.

[Floowid]

My pleasure. I would hate to see that thing have to get trashed. Don't forget to seal the whole inside with 2 part epoxy after you are done. Between the support bracing and protecting whats left of the wood from future water damage, you should be good to go.

I can also tell you that trying to build a curved stand is a real pain the rear end. Its hard to find material that bend around your stand.
