IMO the flow is too intense, are you able to dial it back? I have been running bio-pellets on my reef for 3 years and the guidelines I have learned and operated by are just enough flow to avoid pellets from sticking together. I would call it a steady tumble versus a hurricane.
The issue i have with this reactor it is an AC pump i cant dial it down it is running steady. I might try to find a way to hook it up to my return pump there I can dial it.
