jaco my way of thinking is if i deflect the flow off closley surrounding rockwork it will be fine in my 1.2 untill i get the 1.5 built.. i am also a little concerned about the noise as they are not cheap pumps and i feel they should be completley silent but then again neither is my vortech.. i have actually had friends reach for their cellphones when the pump changes frlo pattern as it is quite noisey.. any chance of an audio on the noise of the polario to let us hear if its really worth making a fuss over?
Just for interest sake ...my noise just disapeared after a few weeks very quite now
