Undetectable Nutrients but still have hair algae

[taintstick]

New clean up crew will help since everything is brand new to them.... but place them directly on the algae.

Sorry we talk to a lot of adults here who don't know what bryopsis is. Its best to double check.

Id get a bigger tooth brush and a bunch more snails.

Yea I get it. What about blue leg hermits? I've heard that those are good for hair algae

Been trying to do that with my Astaeas but they always end back up ok the glass

It looked like you have some, I personally dont like too many crabs. when they run out of food they eat anything.
I have a coral quarantine tank with only snails, I can drop a small rock or frag in and its mostly clean the next morning.

I think they are mostly film algae eaters.

I had a buddy that had some like that, kinda like hair algae. Terrible to try and pull off and when you try to scrub it, kind of just makes it worse haha. Unfortunately you have let it get too bad. I'm sorry, no disrespect. Best thing to do is remove what rock you can and clean in a separate container. You can't leave the lights off long enough to kill it. And you can't try a crazy spot vinegar shot or whatever cause it everywhere.

Scrubbing the bulk of it off, water changes and h202 dosing works best imo for hair algae. Better if you can soak the rock in it but there's too many corals attached. However they can be dipped

I just have a few dwarf red legged hermits

If you can get the longest stuff off tuxedo and pincushion urchins will eat it as will Mexican turbos, trochus snails and red/scarlet leg hermits.

Im a scrub and snail guy myself
If the rock can come out I do like the peroxide dip.

I I had a 150 gallon green hair algae Forest years back... I removed all the corals off the rocks and soak those rocks overnight in five gallon buckets filled with Rodi and a bottle each of hydrogen peroxide. Needless to say they killed the algae and never ever came back LOL. However this was my final battle and I have had enough by this point.

Sometimes its best to pull out the big guns.....

I thought trochus ate only film algae. I kinda don't want to get scarlets due to the size they get

I have about 30 trochus who eat whatever grows on the rock with exception of cyano and bryopsis. Plus they can rite themselves. Yes Scarlets do get large but are harmless unlike blue legs who think astreas are a tasty meal lol. You can also get red legs. Same as Scarlets but don't get as big.

 

[Tristan]

Wow.... have you done a test sample yet with the hydrogen peroxide like I suggested?

Is 3% hydrogen peroxide strong enough?

Yes

In my experience, new astreas will eat the algae cause it's new, but after a week or so they move on. Just get a new clean up crew if you don't want to scrub or remove rock.
If it were me, I'd go grab a big ol hermit from the beach and let him do work but gotta watch him cause they will try to munch coral.

Great then h202 should kill it put some in a bowl with a little water and a splash of h202. If it turns white then h202 will kill that strain. Good luck!

How long will it take to turn white? I am going to be manually removing a little today. If in fact it turns white, what's safe methods of target dosing H2o2?

Or just get a fox face rabbitfish and it will be gone on days. My corals come with green algae on them ans within a day they are bone dry of it.
