I've actually been considering upgrading my standard remora to a 120 or 180. I had one for a different set-up that i was going to sell, so I sold the 180, but now I'm regretting it since I'd tune it in for my 46. I used to get think coffee colored skimmage from my remora. Since i switched it over, the skimmage is lighter. I might be running a light bioload though. hmmm.
