how would i measure how many gallons a tank is what measurements do i take and how would i go about resealing the tank if i know for sure it has a leak in it. its a hexagonal fish tank that is tall and i want to make it into a really beautiful cichlid tank or an angel tank havent decided but i know i want it to be a nice tank.

Measure in inches and do the following:

1. Length X Width X Height = answer

2. Answer divided by 231

3. Round answer to nearest whole number

edit: i made a post, but i've had too many beers to make any sense. my apologies, moderators delete this post please!

I use this. Put in the dimensions then get the liters then use the liters to find the gallons.

Is that still accurate for a hexagonal tank?

morganrules

i dont know

Slug

Oh i didn't even think about that. Probably not....hex's are weird to work with.

Personally, hexs are only good for saltwater. I find it very hard to look in a hex.

morganrules

still how would i measure it to see how many gallons it can hold cuz i want to turn it into a workable tank and i need to know how.

Measure the length, width and height and use a conversion chart.

Here's the link for the Fish Lore conversion chart, scroll down to the bottom.

but how do you measure the width of a hexagon....
and length

Lucy

I'm sorry I missed the whole hex thing!

Ummm, put it in bathtub and start filling it with measuring cups? I wouldn't do this if it's very large.
It would work for a 5g and under though.

Maybe if you measured around it, the height and width across the top, someone may have the same size as you and know how many gallons it is.

ok
thanks lucy youve helped me alot in the past couple days lol

In the end the LxWxH is the same as area of the bottomxHeight.

For Hexagonal tanks, just do the math as follows: measure one side lenght and write it down as measure A, then measure the widht from one side midpoint to the opposite side midpoint, write it down as measure B.

Now use this formulae to calculate surface area 6x(0.5x((A)x(0.5xB))). In other words, multiply B by 0.5 (divide it by two), multiply that value by A, then multiply that value by 0.5 (divide it by two), then multipy by 6.

Now you have the surface area, multiply that by the height of your tank. Divide that number by 231, round to the next number and you got the results in US gallons.

are you sure about that conversion pepe.

Sounds accurate to me.

If all else fails put it in your bathtub and get a gallon jug, and a 5 gall bucket and see how much fits

i just digured it out i have a 43 gallon hexagonal tank YAY
