I have always wondered why folks are so specific........766 gallons, what if you have some gravel and rocks, then you would not get your full 766 gallons right? Is that filled right up to the edge, to get the full volume?
its just what a aqaurium calculator brings up if i said it was 760 gallon then people would acount for the rocks and water line wich would then be 6 gallons off so i just presume people acount for it
