I'm building an indoor pond that is triangular in shape and measures 5'x5'x7' and 2' deep. I really would like to keep a RTC but I'm not sure if it's going to outgrow this mini pond in no time. Any info would be helpful.
Oddball said:I took your measurements of the triangle and adjusted them to a rectangle. Then, it's simply calculating the volume of the rectangle and dividing the results by 2.
Volume of a rectangle: (all measurements in inches)
Length X depth X height/231= volume
I just reshot the measurements through the tank calculator. Mirroring your pond to make a square still comes to 190 gals (187.5). However, calculating a corner tank came to 262.96gals. If the corner of the 2 5ft sections is greater than 90 degrees, the larger volume is the one to go with.
