No. I also have 2 Tunze streams, and there is an Ocean Runner 3500 at one end too, so plenty of movement.
I have a large sump on the other side of the wall, so there is quite a lot more water than you would think, and also a Miracle Mud arae, which has huge amounts of Caulerpa and Cheato to help export nutrients.
I must say, the skimmer is quite busy!
