This customer in the UK has growth that almost looks like green candy in this SURF2 or 2x or 2xx. This scrubber is probably only a few weeks old, because the white Green Grabber rock walls have no growth on them yet. But they will.
This type of Surf growth is very rare, but the beauty of scrubbers is that they grow what they need to grow based on conditions. This one will probably start getting some brown slime on the Green Grabber rock walls, and then on the bottom underneath the green. If more food is given to the tank, the bright green will darken up to consume more of the nutrients (darker growth has more nutrients).
Also very neat with Surf models with this growth, is that you can just reach in and get a handful. Then just set the light back on it, and you are done. Of course if you are getting dark slime because of very high nutrients in the water, you'll still need to take it to your sink for a brushing.
