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?

Using your panels, you can expect to make no more than 1.8 kWhs a day. In reality, you will only see something like 1.1 or 1.2 kWh a day of production. If you want 24/7 aeration, you can see the best you can use is 1.1 kWh/24 hours = 45 watts continual usage. Next you need to see what that will do to your batteries. 45 watts is almost 3 amps multiply that times a 14 hour drawn down over night (winter months) and you will see 42 amps drawn out of your battery or more over night, every night. Your battery will not last very long at that level or usage. Now add some clouds and you can see your problem.

Figure out your load first. Then figure out how much you need to store. Then finally figure out how you are going to produce that much energy.

Don't worry, you are not the first to do it backwards. This is fixable. But start with the load and work your way through the problem.
