At last my SM HOG2 turf scrubber has kicked in and turf/hair algae is starting to grow nicely. I recon in another week or so I will have to do my first harvest of it. With a bit of luck my caulerpa which arrived unnoticed and becoming a pest will die back if not go all together. 2nd pic shows the turf scrubber attached to the sump. A BIG advantage for me is that my scrubber takes up so little space in my sump. I hope to be able to remove my pellet reactor soon or should I leave it there?
