Hey Gord, Thanks for filling that out. The calcium is abit low. Don't know if thats the prob, but try to bump it up some. Also any sign of undesirable algae in a sps system is not good. It is very hard to get readings of a problem as the algae will consume nutrients fast as their produced there for giving you low readings with test kits. I noticed you didn't fill out the maintance area of your tank specs. So not sure what your doing but I would make sure you are performing water changes in the neighborhood of 15 to 25% a month with good ro water and also start running some carbon in a high flow area in your sump. In my experience sps corals will show signs of a problem before stuff like hair algae appears.If you are lacking in the maintance department then I would start it of with doing a larger water change say in the area of 40 to 50% once the algae is gone start expermenting with your water changes and carbon use.This is my best attempt to adress your question.This is my opinion and others might have different ones so please make your own decision based on others opinions and personal research.
