Hey guys & gals I need some help here! I am removing as much grape caulerpa as possible manually, but I just can't get all the roots out and it WILL start to grow back. Surely there is a fish, crab, snail of some kind that will like the stuff and hopefully nip it in the bud when it tries to grow back. I thought about pin cushion urchin, chitons, kole or yellow tang (prefer kole), some kind of snail, nudibrac, or sea hare. Someone else has sure had this problem b/f. Also any kind of chemical algae killer that would be safe for fish? I could remove my mushrooms & tree coral to fuge and disconnect from system temporarily - or I could mix up SW and put rock in tub to treat. Would appreciate anyone who has any suggestions. Thanks, Carolyn
