Might need to slightly adjust the direction of the water flow. Sounds like a PH
might need raising up a tad to keep it from digging up the sand and creating the bare spot. In time the bacteria and detritus will weight the sand down some but only to a certain degree. It won't be enough to counter the force of a strong PH
. A deeper bed would just make a deeper hole.
