Cladophoropsis sundanensis

[Chameleon123]

Well basically its algae and I got it. Low nutrients do nothing to get rid of it. Its an SPS dominated tank with po4 0.01 and nitrate 2ppm or less. I cant find anything on how to rid myself of this algae. Best way to describe it is green scraggly beard. Holds real fast to rock...like you can pick up 4lb rocks before it comes off by pulling. Thinking of trying high Mag or getting an urchin or two. Dont really want urchins because I dont like bulldozers and dont really want to get my chemistry out of whack because corals are growing so good and have excellent color right now. Anyone have experience with this algae and getting rid of it. Its only on uppermost rocks, but rocks are completely encrusted with established acros so treating rocks out of tank isnt an option. I read that low alk can cause it and that may have been my problem as previously I was running a ULNS and the alk was kept around 7.2-7.5 (Red Sea Pro). Since then I have bumped nutrients up a bit and raised alk to around 8.5 with a target of 9-9.5 range. Thanks for any help. I am coming to this forum because I am yet to find answers elsewhere.

Hopefully you'll get an email to bring you back.

I am dealing with this stuff too. Where did your rock come from? Mine was from Sulawesi (Manado) via Premium Aquatics...

Also, what kind of lighting? Full spectrum LED here.

So, High Mag doesn't do it. I ran close to 2000 for a month at least, I'm still in the 1600 range. Loves it. My Alk was a bit low but I'm in the 8-9dKh range consistently now and it's still happy as can be. The more you mess with it, the more it spreads. My only working tactic is hydrogen peroxide, but it's a pretty temporary solution - it comes back. Low nutrients (esp. phosphate) means slower growth and spreading, but let things go for a few days and it takes off again.

Scourge.

I just reorganized my tank into an SPS side and a display fuge side. I'm trying to keep the macros on the display side so thick that they basically light starve the Cladophoropsis. I added an emerald crab to the SPS side and it does seem to pick at it. In combination with spot H202 I may be making some headway, but not sure yet.

Good luck and godspeed.
