What algae and how do I get rid of it???!!!

[Michael43]

Is it just hair algae? It only grows on my frag racks and overflow teeth. Probably because cuc can't get there but snails. It starts to fully engulf frags obviously causing stress or even death to them. I do my best to remove it but it always comes back. Literally none grows on the rock or corals down below. Or it's just being handled there

Looks like HA to me.
Kinda weird it's grows contained only in a few area's.
I would just keep removing it if it's just on frag rack and over flow.
Any test result?
What kind of light you run?

Hydrogen peroxide is your friend here. Take that bad boy out and hose it down with drug store H2O2.

Take the frags off and use diluted peroxide on them. I have used as high as 50/50 but you should start lower.

I believe I'm running same light as you diesel lol. Ati powermodule led/t5 hybrid.

Like just make say I 75/25 water to peroxide mix and dip the corals?

That looks like bryopsis too me. Do the ends of the hairs have fern like fronds?

 

[Michael43]

Not that you say it sort of

 

[Rick.45cal]

Does it look like this?

 

[Michael43]

Sort of but it's a dark brown almost purplish color

 

[Rick.45cal]

Well Hopefully it isn't Bryopsis! Bryopsis is evil.

This stuff does suck. I'm going to completely remove the racks tomorrow and clean them off. Haven't done that yet. Maybe will help.

 

[Bunnee911]

Yes 75/25 or less. Pull off all you can before treating them. A 5 minute dip to start. You can always retreat after several days if you need to. Just don't stress your corals.

The algae should wither and bleach after about 3 days. Your clean up crew will love it.

Don't remember which corals are sensitive. Someone?

I always try to not contact the nontarget flesh areas with the peroxide, then all treatments are nonharmful. takes more work that way, to remove items and detail clean them vs dip, but with that technique there is no coral impact because only the areas that hold the algae anchors are worked over. in our algae removal threads we like to use a metal tool to scrape off the anchored algae first in detail, then use peroxide on the cleaned areas afterwards. the manual removal is a non peroxide part

when using a brush to remove the algae, more is left in place compared to metal

Even when removal isn't the go to option, the tank can be easily drained down a little to expose the patches for work out of water, where scraped mass is easily removed and not cast around the tank
