Well the very little I do have the LMB eat no problem, I turn the 10K lights on the tank and you can see the green on the rocks and it is not filum algae the LMB just keeps it very short and all the snails keep it down and hermits once the coriline algae grows over the area green is gone for good. I've never seen LMB that will not eat HA if it is very short. but to totaly get rig of it you have to get the roos out kind of like crab grass in your lawn and garden.
