Vortex or Koralia?

[mattdean]

I went to ridiculous lengths and expense to make my system quiet. (It's in my office/recording studio) I bought 2 Red Dragon Pumps, Bubble King Skimmer, etc. The vortech is one of the loudest things on the tank, however, I just can't replace it with anything else. the flow is just too perfect and my corals and fish are too happy to mess with it. It's the one thing that was worth having a little noise.
