I have a .75 acre pond, somewhat oval- 12ft deep at a small area at one end the remainder of the pond is about 6.5ft deep. I have a solar setup 300w with controller, battery and inverter. researching what pump and number of difs to run and can not decide on what pump to use. Any recommendations? I have looked at linear and rocking types. has anyone run a setup like this and what pumps worked for you?
