try the following. You will need a gallon jug and a timer.
Fill a 1 gallon jug to the very top and fill your sink with water. Attach a few feet of tubing to your air pump and place it next to the sink. Turn the pump on and have the tubing right there so you can reach it. Put a cap on the jug, turn it upside down, and place the top of the jug underwater. Use one hand to hold the jug while you remove the cap with the other hand. Try to make sure you don't let any air bubbles into the jug and keep the mouth of the jug submerged. Put the air tubing under the water and into the jug. Start the timer. When all of the water has been replaced by air stop the timer. Now multiply the number of seconds by how many gallons your aquarium holds. Now you know how long it takes your pump to exchange all of the air in your tank.<!-/quote-!>
