Green on live Rock

[cbrewer]

We have green stuff on some live Rock, there used to be pink coraline on it, and theres some brown patches of stuff of some also

IMO. Time to beef up the cuc. And get the toothbrush out.

Cyano and gha plus an off one down low.

New tank uglies ?

The green doesn't come off but the brown stuff does

And I'd check nitrate and phosphate especially - something is feeding this stuff and you'll need to control it to achieve a long term cure. How old is your tank? If it was growing coralline algae I assume it fully cycled awhile back.

Can it be from the lights we got new lights a Chinese black box led light 165w. Since we started running it, it's when the green appeared.

It probably both.
New tank uglies and new Lights.

Should we turn lights down, when do you not get new tank ugly anymore

It usually lasts five or six months , assuming good rodi , cleaning and not over feeding.

Turning the light down a bit may help slow it down , but you’ll want cuc and probably a toothbrush as well.

How high above the tank is the light and what are the %?
