Vortech Pump question

I really think you should be okay with one MP10, I have ran one on my 65G when I had it and it was enough! You could also point your returns to assist with dead zones.

It would be awesome if you had a picture of your tank showing your placement, I always found it difficult to determine the perfect postion in regards to my rockwork you might have to change a few times.
