Not quite sure why but my tank is being overrun with brown stringy alge. I tried cleaning it and it's not much better. Been doing water changes but found out after a day that I had my salt at 1.030. Took it down to .025 bit now one of my orbic cardinals is dying. I'm going to keep cleaning and siphoning. I got home late so I'm not going to do more tonight. Just figures. Tank was perfect. Only thing I can think of is I lowered my whites and upped my blues. I keep blowing the sh@t off my corals but ahhhh. Just feeling a bit overwhelmed. I'll do water chem tomm and post. It's been near perfect for a long while.
