It gets nice and big at night about every other week for four or five days. It just started growing this "hair". Is the hair normal?
So - I did a check and believeHow do I get rid of the hair algae? It really isn't under the lights directly, there is a live rock ledge above it that shades it. I've had it in several different places in the tank and it seems happiest with the flow where it is. It has been growing new shoots. I put in some fresh green algae two weeks ago from my algae traps in the sump for the fish & shrimp & crabs. Do you think it attached to the chile? Do I pull it off?
My nitrates are always very low- I don't see any other GHA other than the remnants on chili.Hi... Chili coral needs really strong water flow to keep it free of algae. Also it needs to be under a ledge, or in an open ended cave with a nano power head directed at it, so water can flow over it. Completely out of the light. You have high phosphates and nitrates, test show the wrong readings as low to nothing because the algae feeds on it. Do lots of water changes to try and starve the GHA, the stuff grows fast, and it won't be long before it's out of control.
