Algae - Caulerpa Verticillata aka fuzzy caulerpa

I've been fighting this algae for about two years now after it hitchhiked in. Manuel removal is a down-hill battle. This stuff is tenacious as all get out!!! If anyone has any suggestions on how rid my tank of this nuisance, Caulerpa Verticillata, do tell. I've read that a vlamingi tang should eat it all up, but my tank is only 30 gallons (tiny). I'm thinking of "borrowing" one for a while, but I want to try other options first. My water parameters are great, but maybe it's the algae keeping 'em this way. I swap 5 gallons of water a month, my skimmer works very well, carbon is changed monthly, corals are all very happy when they're not overgrown... I tried a seahare but it never ate the algae so I returned him/her. Also tried mithrax crabs. All to no avail. HELP!!!

 

My experience tells me that adding livestock to battle algae never goes well. Typically this is a water issue. You may want to pick up you water changes to about 10% weekly. You mention carbon changes. Have you tested for phosphates? Do you have a phosphate reactor?

 

I used Algaefix Marine. I did not want to, but I was at wits end. It doesnt completely solve it, but it did weaken it enough to win the battle, along with GFO and good maintenance. Here is my thread if you are interested.

blue leg hermits and rock boring urchins eat it. for sure. I tested it on them earlier this year. Happy I got a got to use the info, haven't seen this menace pop up in a while...

Oh by the way, if you twirl it up when doing manual removal, (use a plastic fork or fingers, and twirl like it was pasta), it is much easier than picking. I had a whole tank setup for this stuff for like 3 weeks. It does grow fast! Spend a day and just get every little bit or in a week you will be right back tot he drawing board. You probably already know it though. Good luck!
