I'm upgrading my powerheads for my tank, and I'm deciding between either the Tunze controllable powerheads (6095 or 6055) or the Icecap gyres (2k). On one side, Tunze powerheads are very reliable and pack in more flow than advertised. On the other side, the gyres will integrate more nicely with Hydros controllers, I will have more options for flow patterns, and they will be cheaper since one WaveEngine can control two pumps. I have heard that Gyres are more of a hassle to clean and need to be done so more often--is this true in your guys' experience? Which one would be the better pick?
