Aquarium Advice Activist
Years ago I bought a acrylic tank, and the store sold it as a 125 gallon. The dimensions are 60"L x 18"W x 24"T. Then a while back I bought another tank, a 90 gallon acrylic. Its dimensions are the same other than the length which 48" instead of 60". Then in researching gallons and size on the web, I found a web site which you put the dimensions of your tank and it gives you the gallons. My 90 checks out exactly, but my supposed 125 comes in at 112 instead of 125. Anyone know what may be going on?
