Currently in my cycling 10 gallon setup I have aragonite sand, white sand blend. I also have 7.2lbs of LR and I will be buying more this coming Friday or Saturday, I have a hang-on-back filter rated for a 20 gallon tank. I know I need a blower in the tank like a Koralia. I just wanted to know what size I need, how many gallons per hour do I need for sufficient water movement?
