Any of you guys have both of these? I have a MP10 and a MP20 in my 29g tank and I swear the MP10 blows waaaay harder than the MP20. I have them both set on Reef Crest. I have the 20 set on max speed and the 10 is on 80%. Does the 10 just push harder cause it is concentrated (like a nozzle on a water hose?
