What is This!!!!

[Psy]

Hi what is this stuff on powerhead and walls. It grows so fast. I have 180gal tank, 5 fish 2 clowns algi blenny, bi color blenny and idk this purple fish same size as bicolor blenny. I feed 2 times a week misty shrimp vary little amounts. I do weekly water change 32gal with bi weekly gfo and carbon change. My corals acropora I have good poly extension and nice color my Acan went from 1 head to 8 in about month 1/2. Montapora is just melting into the rock. But my torch hammer coral are slowly dieing off they where doing good for about 5m. Alk 9.5 cal 430-450 mag 1480.

Chrysophytes perhaps?

 

[saltyfilmfolks]

Agreed.
Run purigen in a reactor or very high flow. Carbon will work too.

Get ready to scrub that stuff out.

Yup, had an issue with this stuff in my sump. My kessil H380 was growing it like crazy. Manual removal won the war for me

what am I doing or what is the cause of it?

 

[HotRocks]

I am no expert here, but I was battling something similar. I went to 25% monthly WCs and changing out GFO bi monthly and it all subsided.

How old is the system?

How old is the system?

1year 1 month

Old school reefer call this mulm. It is best treated with carbon but not to much. It is like a blond hair algae, usually caused by high nitrates.

Are you testing you nutrients?

It’s an alge kinda , that comes in on corals.
Like terrestrial plants and coral do, they excrete a toxin that kills other stuff in the area to out compete it.
The purigen and the carbon should help to pull those toxins out.
I’m told by experts the purigen works much better for it as it’s basically a combination of carbons and other polymers that absorb or allow those origanics to bond to it. Kinda like gfo does to Po4 and a few other things.

That should save the corals and fish.

Manually removing is obviously to reduce the amount of toxins produced. I had an alge So somthing similar. Killed my fuge.

I dunno brother. That’s got a lot of structure to be a mulm.

That is where I am kind of going for, kind of but not

I am thinking a nutrient issue? What do you think @saltyfilmfolks??

Just introduced into the system.
Some of the Chrystos do like and thrive in a nutrient limited system.
The most common culprit is the cotton looking stuff.
Most of that sucess has been to determine what is depleted Po4 or no3 and dose it up to normmal levels while doing manual removal.
Of times with a reactor or canister full of floss. Carbon and gfo. Gfo if it isn’t Po4 limited.
As it’s more closely related to dino flagellates and diatoms than alge , peroxide dosing or dino x may be effective.

So are u saying my tank might be to clean? I'm lost I just started this 1st tank a year ago still learning.

Yes

When is the last time the nutrients were checked?

As JSKER suggested , test the no3 and Po4.
In some cases a limitation of one or the other can encourage growth. In fact some organisms seem to encourage that limitation.

So yea , too Clean kinda.

I run carbon in reactor I change out biweekly

Long time because acropora where growing good with good color. So if I had bad high nutrients lvl my sps would look bad so I dont test I will run some test now.

Tagging @reeferfoxx , she know Chrysto.

Just knowing helps, as @saltyfilmfolks stated to high or too low can cause issues
