if you are tired of looking at the pumps, try hiding it with some live rock. I ended up drilling my tank, but still had the powerheads so I set up the rocks and hand picked a few pieces from my lfs to I could hide the PH. I dont know if it would work for you but it is an idea. I would show you mine but my camera is dead. Instead of buying a new one, i think i am going to buy some sps instead. Back to the live rock, I say a guy who had a "wall" of live rock that was attached by zipcords to a frame. Really nice looking and it was kinda like a false wall because you couldnt see the back of the tank.
BTW it might be a bit late, but the prizm skimmer is priceless. I understand your frustration and assumption that the prizm was leaking. The O-ring of mine warped and sent about 6 gallons onto the floor. Luckly i it just lowered the level of the sump and made me do a water change. Good luck!
