HK53, Ted is absolutely right about adding the never seize. There is nothing more irritating than doing maintenance on a rotary vane and breaking those stupid plastic end caps.
Ted has the exact filter you need for your 0523 and while with him, make sure you talk to him about your diffuser and tubing options.
Roughly calculating using the dimensions you provided, your pond holds approximately 3,670,191 gallons. A desirable turnover rate to ensure proper aeration is to circulate the entire volume at least 0.75 times per day.
An ATI AirPod placed at 9 foot will turnover your pond 1.06 times per day with only 1 cfm of air. At 9 foot, your psi requirement will be 4psi plus whatever lenght and size of pipe you will be using. The 0523 should have no problem doing that.
