I am setting up a new tank 120g (48" across)...I have watched lots of videos and read post after post...I am leaning towards the Nero 5 powerheads (two for my tank) but like the MP40s wet side cleaning and then I see others using one gyre and claiming great flow.
What should I consider - I would like to not just buy and try.
