Tank Calculations

[southern wolf]

Looks like I was mistaken on the size of the bow front I was thinking of getting for my salt tank. Anyone know what size it REALLY is.
It's like they added a bow front onto the front of a 55g tank. It's 4 foot long, 12 inches deep on the sides.. then 18 inches deep in the middle.
Im guessing maybe a 65g bow front but not sure

Go online and do a search for tank sizes, then compare the measurements with your tank. I can't do the math to find the size.

Take LxWxH/231 would give you your gallonage.......

Shawn, is it that easy to measure on a bowfront? I mean, you can do that for square/rectangle tanks, but I would think the formula would look a little bit different for a bowfront...
That formula Shawn said was correct, LxWxH / 231 = volume in gallons, but only for tanks with 90degree angles.
I'm with Flower on this one, you should find out what your dimensions are and then try to find a tank on the internet that has the same measurements, then go from there.

It should put you in the ballpark!!!!

If it's 22" tall then you have a 72g bow.

Cool...I get lost on math like that...too hard.

Cool...what is the 231 number? I understand the LxWxH but why that number?
That's the number of square inches in 1 u.s gallon. LxWxH will get you you're number of total square inches so we divide by 231 to get the gallons.

Thanks, I'm a math cripple but that formula looks easy enough. The stuff I learn on this site....

I couldn't remember the formula for years and for whatever reason it sticks in my head now.....

LOL...I wrote it down so I won't forget.

 

[acrylic51]

I tried that trick to, but could never find or remember where I put the piece of paper.....That's how I started keeping my stuff in binders......

Yep, I have a binder where I put all important information.

How can it be a 72g when the only thing larger than a 55g is the 6 inch bow in the middle. Could the bow really hold another 17g worth of water?

According to aqueon those are the standard dimension for their 72g bow tanks. And according to the tank calculator that I just used which allows you to calculate the volume of different shaped tanks including bow fronts then apparently it does.

 

[florida joe]

36W x 18D x 20H Inches is a 50 gallon bow

 

[2quills]

Here's a good calculator for ya guys for different shaped tanks...http://reef.diesyst.com/volcalc/volcalc.html

 

[florida joe]

Bow front Aquairums
50 Gallon
Aquarium: 36W x 18D x 20H Inches
60 Gallon
Aquarium: 36W x 18D x 24H Inche
75 Gallon
Aquarium: 36W x 18D x 30H Inches
80 Gallon
Aquarium: 48W x 18D x 24H Inches
90 Gallon
Aquarium: 48W x 18D x 30H Inches
100 Gallon
Aquarium: 60W x 18D x 24H Inches
125 Gallon
Aquarium: 60W x 18D x 30H Inches

By what FloridaJoe posted, you either have an 80g tank or a 90g tank depending on the height. You did say it was 48"x18" at the bow, but you never stated how tall it was.

 

[2quills]

Judging by his response in post #14 I think it must have been 22" tall.
