Heyya folks. I recently picked up a Prizm after returning my SeaClone. Anyways, I set'er up and now the impeller will spin but it doesn't seem to have enough strength to pull water up the intake tube. I primed it and primed it until finally the water is at the top and the water somewhat..."chup-chup-chup"...it's hard to describe...Anyways, it's been nearly a month now with a skimmer and I do frequent water changes and everything is fine so far, but I'd like to get this going. Any help is greatly appreciated.
