Which would be more beneficial?

I wouldn't waste that much money on a mp-10 for that big of tank, 4 k-1400 placed around the tank would do a better job. yes the lil mp-10 is a beast but the flow pattern is very narrow because its made for short tanks. so maybe some k-1400 and a controller .

Makes sense..... Might try the mp 10 from my nano and see how it works first..
