Hi all, I was interested in what mode people are running there power heads on, and what your thoughts are on the NTM/TSM modes. I'm running two MP40ES's on my AGA180, and mostly run them in "Reef Crest Random" mode. I also have a short puls wave that makes about a 1"- 1 1/2" wave at the top. I am a little worried that a wave will harm the tank, so I only run it for 30 minutes when I'm looking at the tank. I haven't noticed much with the pumps in NTM or TSM modes, but I don't have any pumps on the back wall, like suggested by Eco Tech, anyone using mp's on the back of the tank?
