ok sorry didnt realize you were talking about an oval....if i remember right i finally decided on something around a 20 foot diameter. ill have to find the plans and then ill post the actual but im pretty sure its around 20ish...maybe alittle less. Bill i thought about that but its just too hard to light a tank that deep IMO...even with all natural light you wont get a full days worth of sunlight into the tank and remeber that around the equator its about 12 hours of night and day all year long where as here in Nevada it isnt quite that much but it still might be ok.
