Good stone for fish pondNov 10, 2011
By Marc R. Baril
I needed a large pond stone for a relatively small fish pond (50 sqft x 2 feet deep). This fit the bill perfectly. It is sufficiently weighted that it stays put on the bottom of the pond and has sufficient area that the required driving pressure is negligible compared to the hydrostatic pressure required to drive air into a 2 foot deep pond. Note that the inlet port is for 3/8 ID tubing, so an adapter is required if you use an aquarium style air pump with the regular tubing. I'm driving the stone with nothing more than a tetra Whisper AP 150 and this really gets the water moving around. I suspect that the 6" stone would probably work just as well.
