That's weird that different calculators give different measurment unless I am not understanding the results. You say your tank is 770 gallons, but the MFK calculator says 898 gallons at those dimension, why is that? Also akliaz33, I sent you a PM, did it come through?It's actually only 770 and it has been a huge headache, but I think once I get it up and running it will make me happy to the third power as well.
