ciculation question

[martym]

Tank is drilled, but I would mount the pumps behind the tank and draw the water out that way, that's why i figured two mag9 or 12's would work. It's hard to move power heads to where they would work best because they are so focused. The 802's move alot of water but the MJ 900's don't. I was going to get some 402's but I was unable to be where I was suppose to be to get them .
