Can someone identify this algae? And how can I get rid of it? When I rescaped my tank I pulled all rock from the tank and scrubbed 98% of it off and now it’s coming back.

GHA. How old it the tank? It's usually just part of the maturing process. What size tank and clean up crew? Either way I recommend dosing live phyto.

Looks like it could be bryopsis. @vetteguy53081 what you think? If it is, it can be a monster. Fluconazole can work, but mine JUST KEEPS COMING BACK!!

He's on a cruise atm.

Tank is 1.5 years, 120 gallons. I culture Nannochloropsis phyto so how much should I be dosing? I had urchins from the last time I was fighting it. One pincushion and a tuxedo in my sump. There is a long spine in there as well but I didn’t sump him because he never leaves the rocks and moves frags!

Okay. Bummer. If you can get a close look at it, GHA tends to have a single strand from the base. It's fairly easy to pull off of the rock. Bryopsis tends to have more of a branching look (kind of what it looks like). It also has a stronger hold at the base. Take a close look and see what you think.

No snails or crabs? Get the 100g package from reeflceaners.org as for the phyto somewhere around 20ml to start daily.

@AlgaeBarn
Might as well try and drag in the big guns lol

I do have snails and crabs…probably need to replenish their numbers as I had a pair of blue jaws in the tank about 6 months ago. Lots of nassarius but they don’t do any good on the rocks! It’s definitely not bryopsis unless there is some different species out there. My reefing buddy has a 10 gallon macro tank just growing random algaes and he was breeding lettuce sea slugs for a while and they wiped out all of his bryopsis, his looked like a tiny fern. Mine literally looks like a shaggy stuffed animal was dunked in the water. I have chaeto in my fuge that’s growing good, maybe I need to up the photo period? It’s on roughly 10 hours a night because I have problems keeping nitrates up so I cut it back from 14 hours.

I'd still get the 90g package from reefcleaners. It'll add diversity. Manual removal and the phyto will all help.

I just submitted my tank info to him for a custom cuc. I bought a boat load of dwarf ceriths not long ago and pretty much all of their packages contain them. Frankly I hate the little suckers, they climb out of the tank and jam up powerheads like none other!

This is GHa with GHA built over itself like a carpet. This will need some labor . . . . pull everything you possibly can by hand then reduce white lighting. Assure your phosphate is not elevated.
Is this tank by chance at or near a window?
Next take a pipette or small turkey baster and squirt some 3% peroxide at the base of the algae. Then add cleaners such as: astrea, nassarius, trochus and ninja star snails and even 12 carribean blue leg hermits and a pencil urchin for added control

 

[Derrick0580]

The window it is near is between two houses in a subdivision so 12ft apart, doesn’t get direct sunlight as the blinds are closed 90% of the time unless it’s nice enough to open windows. Before last weekend it was on a wall between 2 windows between the same houses and didn’t get direct sunlight. Hanna ULR phosphate test reads 0.04. I scrubbed most of it off a month or so ago and its started coming back. I have a tuxedo and pincushion urchin in my sump, a long spine still in the tank because he doesn’t come off the rock and carry off frags. Do I need a pencil or can I put the other two back in display?

I am not sure its algae. Though algae is very common, the color makes me wonder if it might cyanobacteria?

Definitely not cyano, it doesn’t just lift off. It is stuck down and has to be physically pulled off.
