get a black sailfin blenny and go to reefermadness.com and get one of the clean up crew packages. totally get rid of any hair algae you might want to try a scopas tang. hopefully this gives you an idea. how is your water quality? are you doing water changes 10% a week?

Phosphates are too high. Water changes help, likewise skimming, phosban, once you can get cleanup to eat the stuff. It's a pita, but a tank-age issue. Tests won't show phosphate as long as the algae is alive and having sucked it up. But it's in there.

I agree. Get to the source of the problem and deal with it there. Either phosphates or nitrates are to blame. Do you test regularly, and what are those levels?

what is a good phosphate test kit. and does phosban work well

get the salifert test kit for phosphate...do 10-15% water changes weekly. also if you have the time, take each rock out one by one and place in a bucket of saltwater, scrub down each rock with a new clean toothbrush soft bristled and get as much of that stuff off as possible

the only thing I have been having luck with in my year and a half long battle with bryopsis are Chaeto, Mythrax Crabs, and a Blenny (mine's a LMB).

I have the chaeto in-tank (no fuge on this one) and it doubles in size every 2 weeks. I harvest the new growth and put the old ball back into the tank. I have seen steady reduction in the hair algae's ability to grow and hold territory.

I'm speaking from experience....the best way to control any type of algae outbreaks is to find the source the algae is feeding on and control it. Phosban, snails, crabs, and grazing fish are ALL band-aid solutions. Dont get me wrong, snails\crabs\tangs are good to have - but they are not the solution. Phosban is another band-aid fix in my opinion.

If you want to get to the root of the problem...answer these questions first:

1. what water are u using for water changes and top off? Did u test the water for nitrates and phosphates?

2. Are you feeding a lot of flake food or other phosphate-rich foods?

3. Do u have any macro algae (cheato, etc...) to help control nitrates?

all the above are good ideas, fight the battle at the source of the PO4.

As far as critters try a lettuce nudi... Hermits, Snails, etc...
