Not sure where the best place is to post this so I will throw it in here. I have a minor hair algae issue in a SPS dominated tank. I can usually eliminate it by using a combination of running GFO, watching feedings, and using a bacteria product such as Vibrant. By doing that though, I eliminate the nutrients that the SPS need to thrive. What is the best way to fight algae issues, without affecting the coral?

I used to have some luck with large cowries but those are now eaten as well.
