Wanted to get an actual tank related discussion going... 
In your opinion, have we reached the point where closed loops are becoming obsolete?
If one Vortech can pump 3000gph, and two can be linked together to form alternating currents, is there an argument left for closed loop systems? I've read more than a couple of tanks build that say that they actually had to turn the unit down. It was too much flow for the LPS and softies.
Also, anyone making powerheads is going to have to come out with something comparable or better. Not to mention with LEDs making significant improvements monthly, are we on the cusp of the next generation of reef keeping?
