Help ID and Treatment please!

[Mikhail728]

Greetings everyone! I searched and searched to find a possible ID and treatment for my issue and I can't quite find what it is.

Tank: 75gal 15sump, parameters are all within range. Nitrates reading 0 and phosphates reading .04 Red Sea kit. 2 evergrow leds 1: nova a8 and a 120w led cluster for got the name.

I'm running gfo/carbon, skimming somewhat wet and have some dragons breath and chateo in the sump.

I attempted a 3 day blackout and status of the mysterious stuff hasn't changed.

A couple pics:

Worst of it

About mid tank

Lower to mid

And sand bed(got a pic of my goby and pistol! Rare find haha)

Some info:

It used to be clear like peach fuzz but gained some brown tint to it since a couple of weeks has passed.

No bubbles forming unless it was caught drifting by.

It only forms on parts of the rocks that have high concentration of light. None in shaded regions

Nothing on sand, some on glass, power heads, and overflow box.

It's hard to come off scrubbing with a brush or fingernail.

My clean up crew eats it and stops(all still alive).

I dimmed the blues and whites to nothing for a week and no improvements.

Attempted 3 day blackout with no help!

Thank you for your time!!

Anyone have any ideas?

It's a filamentous algae similar to green hair algae but with not much chlorophyll. You can either let it run it's course with a heavy clean up crew or start a cheato reactor or algae turf scrubber. Never the less it's part of the maturation process new tank go through.

Never mind just saw this. I would let it run its course.

Gfo running for 3 weeks and chateo a couple of days, its the main reason why I went this route to combat the algae! Thanks for the input

That’s not normal maturation of a new tank.
I think he has chrysophytes...

Is it a golden color and somewhat snotty looking?

Probably best to remove the GFO so the macro algae has nutrients to grow. Since nitrates are low, you could work on more fish or feed a little more often.

It's not snotty its filamentous. Chrysophytes will blow off the rock easily and can make the water look like it's snowing. Here is a video of when I had chrysophytes.

buhhhhh, nasty!
I saw it in another reefer’s tank, hideous stuff!!
Weirdest, snottiest looking algae I’d ever seen...

Probably the most easiest to remove though. Took me 3 days to eradicate.

Reefer fox,what exactly did you do about the crysophytes?

Let me add, I battle this crud for 6 months throwing an arsenal of bottled stuff and anecdotal fixes anyone could come up with. But mostly it was because we couldn't ID it. We had a microscope image showing chlorophyll and the assumption was golden algae. Luckily scientists included that nickname in their ID as well. So we learned it was a photosythetic silica based algae.. Took me a couple of week to figure out a regimen to remove as it's regrowth was fast but here is the schedule and the short version. Some things have to be monitored if coral are present. This consists of manual removal, black out, and 24 hour gfo treatment.

Day 1

• First thing, scrub rocks with a toothbrush while filtering with canister or floss. Remember to check floss or sock for clogging. Make sure you get as much out as possible. Wait till tank clears.
• Perform black out. (ie: cardboard, trashbags, no light, etc)
• Add recommended amount of GFO for tank size to overflow or reactor. Start 24 hour timer.

Day 2

• First thing, check alkalinity if you haven't.
• Prepare to turn GFO off.

Day 3

• Or 72 hours later, remove black out procedures.
• Slowly acclimate the lighting back to normal to reduce stress.
• Your snails should start eating what's left.

Thank You Sir !


& Thank You Mikhail for me butting in. Hope Ya find out what your brown stuff is.

Not snotty and more of a brown hue?
