Well it points out nutrients in your water column. It won't go away, that's for sure. One bubble turns into two and so on until the nutrient levels in the system are absorbed. This is why algae turf scrubbers are effective, but it is simply putting the algae in a different location...same with a refugium. I once discovered a cluster of bubble algae in my tank behind the rocks the size of a fist. I simply rehoused it into my refugium. It is doing a job after all.
