thinking about messing around with flow

I've started experimenting with the flow setup so I get laminar flow across the entire tank. I'm aiming for a nominal flowrate of 0.5in/sec.

To aid in the experiment I planted ~100 stems across the tank so I can see how the water is moving. I'm giving them a little while to grow and establish a foothold.

I'm going to make 10 or so little acrylic panels that will be drilled and slotted in various ways. They'll act as supply/return baffles and will be removable. This will give me flexibility to experiment until I find the baffle combination I like the most.
