I have two powerheads at opposite ends of my tank, pointing toward the center.
One of the powerheads has occasionally become dislodged from it's suction cup mounting. When that happens, my sand bed is blown all over the tank.
I've read that once a good DSB is established, it's harmful to the organizisms to stir up the bed. I was away today when my powerhead can unattached. My sand bed was blown all over the tank (in some spots nearly to the glass bottom).
How do most of you guys mount your powerheads? Do you use some DIY, no suction cup mountings?
Thanks.
