I would just get a powerhead instead. You can get MaxiJets for $12 to $18 apiece and they are good quality powerheads. I would not use tap water. Conditioning it does not remove all heavy metals or phosphates or nitrates. Lots of people that use tap water run into major algae problems. And it's true that water conditioners will screw up your protein skimmer. If you are going to buy a skimmer, you'll have to switch to RODI water (which you should do anyways, in my opinion).
