MP10 not pushing much water ,, options ?

[Coralgurl]

I had an MP10 on my 55 gl, wasn't enough so added the MP40. You don't have to sync them, just have them on the same setting, MP 10 at full, MP 40 at 50% and you are good, or adjust as needed. I have 2 MP40's on my 180, they are synced, and run at the same speed.
