I just wanted tell you guys about my air pump. It's a Supreme Pondmaster 100 and can produce enough air for 10,000 gallons of water. Can pump air down 11.5 feet, 9150 cu.in/min and weighs a woping 16.5lbs. So do you think it's overkill for 565 gallons of water.
I also would like to se what you guys have setup.
