Hi, I am new to this forum and have been trying to educate myself on aeration. My pond is approximately 1/3 acre with a small island and the average depth is 6 feet. I would like to use 2 diffusers, one at the deepest area (8 feet) and the other on the opposite side of the island (6 feet). My budget is pretty limited so I've been researching pump options. Is anyone familiar with Blue Diamond pumps? I found an ET120 for less than $200. Also I am considering installing the pump in my basement and running one tube underground to the pond which is 100 feet away then splitting it using two 50 foot weighted tubes to the diffusers. Any comments or suggestions would be greatly appreciated. A diffuser recommendation would be great too. One final question, would installing the pump in the basement create any issues by pumping cooler air into the pond?
