Wow, looking great! Can you reduce the resistance in the DWR by trimming the roots a little, IF it becomes an issue that is?
I need to look up the yamabuki lift, looks interesting. What sizes are you FT and total grow area?

No idea about triming the roots but the idea is to run the water between the roots.
Fish tank is 8 feet in diameter and about 600 gallons. 200 6 to 8 inch tilapia. I did have another 100 bluegills in there also but they were moved to an indoor tank yesterday.
The raft tank is 4 X12 feet.
