Hey Tankful :
I see now how cubic inches are converted to gallons. I found out I have a ¼ cylinder aquarium. when I did the math I came up with 67 gal this can not be right. Try again…PI x R squared x height x .0044 = gallons / 4
3.14 x 729 x 23 x. 0044 / 4 = 57 gal. don’t believe the aquarium is this large no way did I tote that much water.
I will go with your 36 gal. answer.
Somehow gallon rating seems non useful to me. What good is volume measurement when so much area is taken by substrate, deep sand beds, plants and other decorations means a 40 gal aquarium might actually be rated 30 or even 25 gals of available water..
