I think I've finally nailed down the size of my pond. The main triangle is 11x14x4, which if it were square comes out to 4620 gallons. Divide that in half since it's a triangle and you get 2300, which is what I thought the whole pond was using this other tool. Then The far tip is an oval 8x6x3. That gives me another full 1100 gallons so I'm looking at 3400 gallons total. What do you guys think, does my pond look like a 3400 gallon pond? That's a huge volume more than I originally figured, and if it's right, I'd say I can definitely add some butterflies and probably some more regular ones. So how does this math sound?
