Hair algae, the bane of reef keeping.
Some of Deb,s suggestions are good ones. Although I have just seen extra current make wavey algae instead.
Direct it at places in the rock where detritus can settle, as thats helping fuel algae growth. Any detritus collecting in the cc, will increase the phospate, which again is fuel. Perhaps try some Phosban, a Two Little Fishies product. Ask Rick if he has it.
Then crop the algae short by hand, as the algae eaters dont like long hairy stuff, then as much as your budget can allow;
---add lots of good turbos, I prefer what Jayson calls Deepwater Turbos.
---- add a pair of urchins. Best algae eaters I have seen, but may knock a few things around for awile. Also need to place them on the algae now & then and WATCH the spines. I recieved a puncture once and it got infected.
Also Deb,s other suggestion about some other form of competing algae, would help. It could be in a sump type algae filter or even for now, in the tank. Jayson has some dandy kinds of seagrass & calerpa,s for sale now. Although I have not used the seagrass type stuff as a nutrient sponge. Just some plain old calerpa in a sump may help. Put some base rock or something in there, for it to attach to. I dont like the sand in there myself, as it becomes another nurient trap, unless cleaned very regular. Make sure the light is enough to compete with the tanks algae.
My preference is still the algae eaters in the tank. I really dont like sumps full of calerpa, although it works, until it craps.
