My cyano is still going strong too. For you guys with vortec pumps, whats your ideal pump placement on a 50 gallon cube? I trimmed down my rock scape so it's not so obstructive in the center, though I'm still not done with it. It used to be a tall "C shaped" mountainous structure.
Worst picture ever, but the MP10's are placed about 5-6" below water line running random mode (yellow) at around 85-80%, slave is orange knob.
The majority of the cyano is on the sand bed in the front of the tank.
