MP-10's would be too small for that tank.
2 MP-40's would be the way to go. You can dial them down to control the flow which is far better than running them WFO which makes a lot of noise. Additionally, when you get into the Vortech pumps, you have to consider that it's not all about GPM for flow, it's about watching what is happening in the tank. I have a 40 on my 60 cube and also run a K3 koralia to keep good flow all over the tank. I considered adding a second MP40 or an MP10 to supplement, but right now it's too expensive.
But again, you would be looking at 2 MP-40's on a 100. Not MP-10's.
