Here is the kicker... I've had this tank for years. I've never put any colupra or alga in it. I haven't added LR for years. Also, Over the past 3 weeks this stuff has gone wild. Anyone know how or why?
I noticed the colupra is heading towards the oysters blow hole. At the rate this stuff is growing and attaching itself to corals I don't want to strangle anything.
Here is a better picture.
My Hippo tang hasn't even munched on it. I was hoping he would keep it in check.
