Been on vacation for about 10 days or so. Got back today and I have which looks like hair algea growing all over the glass. Also all my coraline algea seems to disappear. My tank looks like crap. I tested my water and everything was within range. What made this happen and what do I need to do to try and get rid of it? My plan is to shut tank down. Scrape algea off glass and then change some water. Does this sound about right? On the happy side all my fish are accounted for. But I did lose some corals.
