TSM has been working well for me on 4 foot tank. I have 3 MP40s, 2 at the ends & one at center back glass. They're in a master/slave grouping but I have the one on the back glass limited to about 50%, not sure, but certainly doesn't ramp up as high as the other two during the mode cycle. My tank is narrow front to back, I would have preferred an MP10 on the back glass, but the MP40 speed limited works well enough. Without the pump on the back glass I would for sure have a lack of flow in the middle. The most quiet places in my tank are at the ends on the bottom & corners.

Occasionally I'll put them into NTM since that's a single button push. I took the time to tune a nice wave when they're in that mode, so works great at stirring things up. Also do that an hour or so before water changes.

What you might consider is changing your MP10 for a 40. Then you'll have more flow at lower settings & the 50% minimum with the MP10 won't be required. You can always limit the maximum speed of the 40 as I'm doing with the one on my back glass.
