I currently am using a wet dry trickle filter as well as live rock and live sand in a 90 gallon tank. The inhabitants include three damsels two perculas about 30- 40 pounds of mixed live rock and 3-4 inches of live aragonite sand. Things are going fine everything is thriving as long as I change around 20 gallons of water a month. Will removing the bio media in my wet dry trickle filter improve my water quality to the degree that water changes are no longer needed or are needed less frequently? If you would kindly point me in the right direction I would greatly appreciate the insight. Thanks. Richard Slocum
