Odd question

[Kirkslittlereef]

Ok I’m finding conflicting information on how many gallons my tank actually is, I see everything from 105-125 gallons for a 60x18x24 tank. Anyone know what the actual gallons would be?

112 US Gallons or 425 liters

I was trying to figure out how these tank manufacturers were coming up with 125 gallons with those dimensions ‍

I wonder if some of these calculations look better if they are done under blue lights?

The hobby has a long history of rounding (errors), or using approximate gallons of the glass box to name these mass produced tanks. 125 is a nicer number than 106, and after 100 the tank is so big that most people may never actually know how many gallons it really holds.

It is not a science based naming system like cubic inches or liters of engine used commonly in the automobile mfg business. I wonder how many cu inches of piston displacement are in a Tesla engine?

There are some on line helps Marine Depot (free plug)!

I figured once it has rock and sand in it it will probably be closer to 100 actual gallons of water

I used the calculator to figure out the "volume" but after I added rock I have drained it (once or twice) to figure out how much water is actually in the tank. I have 2 tanks and a sump that full and running hold 150 gallons of sea water. I think the two tanks were rated at "125" and "40" not counting the sump. So the mfgr numbers tend to be approximations that may or may not be useful if you need to know how much water you actually have.

Plus sump =125.
A pro clear 230 is 180 + 50 sump. (On or about)
Great marketing

Depends on glass thickness, any bottom sheet, water level height, and how much rock and sand.

My tank holds about 140 US gallons ( but the size is typically referred to as a 150). With sand and rock added, it holds 110 US gallons (measured when I filled it).
