can i ask u guys here how much is 1 gallon of water?
a 2 feet(2 feet long,11/2 tall) tank is how many gallons?

Just gotta do some measuring, and math!

Measure the length, width, and heigth of your tank. Multiply those 3 numbers together to get the volume (if you measure in centimeters, you get a measure in cubic centimeters or "cc". 1 cc =1 milliliter, or 1000 cc = 1 liter). Once you have a volume in liters, you can convert it to gallons. I'm not sure, but I think 10 liters is about 2 and a half gallons....probably your best bet is to find the exact conversion online!

also, 1 US gallon = 231.000001 cubic inches

so in inches length X width X height divide by 231 gets you gallons
