I built an "L" shaped spray bar using 3/4" PVC in an attempt to gently push more water toward my overflow in my 90g tank (1 overflow on the left side of the tank). It seems like theres a small amount of debris that just spins vertically in the tank and doesn't make it's way to the overflow.
As an experiment I plucked a leaf from one of my plants and it's been gently tumbling in a vertical circle all afternoon.
I should mention that my spray bar is under the water level spraying up at an angle to create surface distortion and pump is a CA 4000
Is this a sign of too little flow, too much? A problem of Spray bar placement?
Any opinions welcome!
Thanks in advance.
