Oh no, Neomeris annulata! HELP

[Predom]

I've been in the Hobby for a little while now, My tank ATM is a 55Gal that i picked up from a friend when he moved to a 160+Gal. Currently i'm having issues with some pest algae and after trying my hand at getting rid of it a few times i've decided to accept help!

I'm not 100% sure where or when i got Neomeris annulata but the whole time i've had it i didn't want it. The first method of removal that i tried was mechanical removal, i put my hands into the tank and pulled them off the rock, worked well enough when there were only a few of them in there i guess, i mean i could only get the big ones, the small ones that are tight against the rock elude me entirely. the second method i tried was buying Mexican turbo snails, i felt like they were doing good work for about a week, they ate quite a bit of it or at least i thought they ate quite a bit of it, they don't seem to be doing so anymore.

i have a 35 Gal sump/refugeum filled with chado and a little bit of calerpa(spelling?) my lighting setup is a DIY LED setup from RapidLED 36 3wLED's 2/3 blue/royal blue and 1/3 white.

Calc around 450
Alk around 12 i think, haven't had time to test this week
Phosphate and nitrate are low, my test kit doesn't pick up anything.

Pics are just taken from my phone so i'm sorry for the blinding white glare.

Oh i Forgot, also at one point i took the worst two rocks i had and threw them into my sump, that slipped my mind when i was posting

i am so sorry to hear this. i have never face this problem but for what my knowledge is this is extremely hard to rid of. it even survives in sealed dark un-circulated water buckets.
the only thing i can think of is to out-compete it buy adding caulerpa in ur sump.
maybe someone else can chime better on it, sorry.

 

[Predom]

Yeah i don't know what i did to deserve this like i said i do have caulerpa in my sump along with chado. I heard from someone that you can use hydrogen peroxide to get rid of this stuff, but without talking with someone esle who has used this method before i'm not ready to take the risk of doing it(whatever it is) without someone to guide me through it.

Thanks for the post bnumair

 

[Dr. Reef]

yup i would also see if someone else can chime on it as i personally have not done so. good luck.

No progress so far with just another water change and some manual removal, any help would be greatly appreciated. thank you.

I would remove those pieces and just throw them away before it gets worse. I have seen a couple of threads on here that were scary. And improve tank maintenance habits for a long term solution. Good luck.

Update Time

So today after pretty much doing nothing new since day 1 i decided to take action! I decided to treat all the live rock in my sump with H2O2 (Hydrogen Peroxide) i'd read a few Tid bits around reef web pages and decided that it's probably my only real option.

After thinking about it for a few hours i decided that doing all of my live rock at once might be a little much, i expected a good amount of die off, and with that should come excess nutrients so for today i did the LR in my sump , and the left side of my display.

I filled one 5gal bucket with tank water as a rinse and made a 3l solution of 50/50 tank water and peroxide, each rock got a 2-3 min soak in the h202 followed by at least the same amount of time in the rinse, after which they returned to my display.

i took two photo's of my tank after the dip(really should have taken some before too so you could see how bad it was getting) the changes area amazing, but i'm sure with the good comes the bad! in my rinse bucket i had probably 30+ dead brittle worms, and even though i did my best to make sure none of my livestock ended up going through the h2o2 i had a snail that accidentally took a swim.

I'm not sure how long i should wait to do the second half of my tank but i don't think it should be too long or it will just come back right? but at the same time i feel like it really kills the live rock, am i wrong to wait? how long is too long?

as you can see from comparing the top pics with the new pics, the tank had become much worse since my last pics.

don't be strangers.

For something like that ideally when you first see it you just toss out the rock it's on. But it's on a lot of your rocks and your rockscaping is gorgeous. You could kill the rocks and reintroduce them later. I know with Bryopis, some have success with elevated Mg levels, maybe you could try that? I'm sorry, no clue. Maybe someone will have an answer. But at least it's kind of pretty.

How does one get RID OF IT?
