I had not run a skimmer on my tank for the past 2 years. Now, I am paying for it with some soft, long green-hair algae in a many locations. It can be removed easily with a bit of gentle scrubbing with a brush. Because of the outbreak, I started skimming 24 / 7. Now the polyp extension on one of my chalice corals is very poor at night. Before it was so extremely happy with fabulous polyp extension. My plan is to skim 1:00 AM to 11:00 AM daily. Any thoughts?
