New to the pond world, but one thing I've picked up already is that I need aeration.
I've designed (on paper) a bottom aeration system, but I'm having difficulty figuring out if I can get away with an energy efficient diaphragm pump. Something that's relatively quiet and low on power consumption.
Here's what I think I've figured out:
Estimating on the high side I think I've got about 90,000 gallons.
If I can get 2CFMs at the diffusers, the pond will turnover about every 5 hours. I can run overnight for 10hrs.
If I put one diffuser in the deepest part ~7', and another at ~ 4', I'll need 5.5 psi.
The PSI is what's tripping me up. With my small pond, even the HiBlow 80 pumps much more than enough CFM, but not even the HiBlow 120 operates with enough PSI. Can this be right?
The below setup is what I plan to use, assuming I can find the right pump. Below that is a terrible google maps image of my pond with my scribbles all over it. Below that is an actual photo of the pond.
I'll take any advice the smart people of Pond Boss would like to give.
Thanks! - Jerry
