Currently I have an MP40 on my 57gallon Deep Blue tank. I run it in reefcrest mode at about 50% and while I like the flow, it doesn't seem random enough for me and would like to either ad a pump on the opposite side of the tank, or get rid of it and start over. I don't think I want another MP40 just due to price and an MP10 doesn't really stay put on the tank due to the glass thickness. I was thinking of either two Nero3s or Two Nero 5s. Or two Tunze 6055. What are your thoughts?
