If you enjoy the pond you have now just wait until you get the larger one cooking. Your on your way to the three pond big or at least it seemed so when you found out it would be 800 gallons , after all it sounds like a very big number. But then next comes the 3000 gallon pond, and that suffices a couple years then some more to the 5 or 6 thousand gallon ponders. Then you have the nut jobs like myself my wife calls me the incredible Mr Limpet . FOR THOSE OF YOU WHO REMEMBER THAT MOVIE.. I do admit i wish i wish i was a fish ......... And yes I too highly recommend the bog ...... One of the largest advantages to the bog that i feel is the ability to fit any shape or size requirements you might have. it can be long and skinny or short and fat shallow or deep .
