Hi all,\n\nMy tank is finally cycled but overgrown by long green algae (water is ok i think: 0 ammonia; 0 nitrites; 15ppm nitrAtes; ph 8.3). \n\nEnter my first algae grazers: 3 Red clawed hermit crabs - they didn't move from a spot in 24h; an Algae Blenny/Sailfin - turned out to be a mistake for my small tank although he seems to be feeding on the live rock (I'll probably end up giving it to someone with a bigger tank if he starves). None of the above showed any appetite for these long hair-like green algae. \n\nI'm disappointed with the Red claws who haven't moved at all since I got them yesterday. I've had a small blue hermit in the tank for a while and he survived through the last part of cycling. What's wrong with this picture?\n\nThank you all.\n\nPS: I read here that green algae may interfere with symbiotic algae of the corals. It doesn't seem wise to add any corals in till the algae are controlled, right?
