Barracuda higher than sump
Ok I finally moved the pump lower than the sump
My question now is can you give me any ideas on how to secure the pump to the stand with the liner in place? Or will the weight of the water and pic hold the pump in place?

The green padding is for sound only
Even after the pump it would have done the same thing. You could have put it right after the discharge. Putting restrictions on the suction side of a pump is asking for trouble.
