For a quick and dirty computation keep in mind that a gallon of water is 7.5 cubic feet so calculate the cubic feet take 3 fourths of it then add a 0.
In your case 3 fourths of 4 is 3 times 2 is 6 times 2 is 12 adding a 0 is 120 gallons

Try this computation out. You don't need to be a professor to do it lik Bob here.
your tank is 119.7g

Tangs are ment for long tanks, or common tanks. So when you see that they are better suited for a 125g tank, they are refering to a 72"x18"x21" tank. The back and forth swim room is what they are looking for in the tank.

Will if you wanna get really really technical and have a calculator handy take the cubic inches and divide by 231. The 3/4 of cubic feet and an added 0 I think most people could do in their head in a pinch.

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)
