About 243 litres, its that really small height that makes it so smallUmmm... I kind of have a problem... The mfk tank calculator shows up funny on my phone and my math is terrible...
How much water will the 6'x1.5'x1' hold? Because my math is telling me that it only holds like 300ltrsish... I'm doing the math wrong, right? Because it couldn't hold less than my 5'... Could it?
