Closed loop RD3 230 with different profiles for different times of day. Internal flow is handled by 2 Tunze 6205's and 1 Tunze 6105 in the main display, two Tunze 6095's in the display fuge, 2 Tunze 6055's in the frag tank all controlled by my Apex and or Profilux depending on the tank. Also have a pair of Neptune/Apex WAV's in another tank here.
