Any other experiences with them on a wavemaker? I was using MJ12's on a wavemaker, but I need powerheads that "push" water rather than "stream" it, like Koralia's or Seio's.
(I had the MJ suction cups come loose and it shot the water upwards, emptying the entire frag tank, ouch)
I'm trying stay cost effective, since it's just for a frag tank.
I would be curious if they leak any stray voltage into the tank. For me a huge benefit to the Tunze's was that they run on 12 volts and not 120 volts.
