powerhead woes

[magern2]

I have been using powerheads to circulate water around the tank, but the suckers that attach the powerhead to the wall of the tank always fail and the powerhead drops down and mess up the sand bed. Am I the only one with this problem and is there any lasting solution for it?

Hi,

Ever tried using your rocks to support the base of your powerhead and using the suckers to keep it in place? Well, the suckers tend to harden after awhile and lose its suction strength. Thats why u have this problem

never trust suckers man... they are like a time bomb waiting to happen...

My powerheads are all mechanically hooked onto the glass with the hooks provided with the pumps...
