GHA or Bryopsis

[cmcoker]

I had this algae take hold last year, I have since broken down that tank. I pressure washed, scrubbed and dried out the rock and have setup another tank and no sight of it so far... I still have a few rocks that have corals that couldn't be removed in an 10g tank currently. I've done manual removal, peroxide, etc.
I never measured high no3 or po4 but assumed the algae was consuming it. I never noticed the fronds always mentioned with bryopsis so thought it was GHA, but reading through the fluconazole x bryopsis thread someone mentioned their bryopsis growing in high flow areas. That sounded familiar to me, as that's where this algae prefers.. I decided to tank a closer look and this algae has what my wife described as looking like "split ends"
So thoughts?

I can try to get a microscope picture, maybe tomorrow. This was the best I could get today.

That close up it looks like bryposis. No clue what GHA looks like close up so hard to say. I will say I do get a few pieces of bryopsis on my frag rack for my SPS which is in very high flow...

I have had bryopsis before and that doesnt look like it to me. Bryopsis looks like a fern..

Where did u get the sample from? Bryopsis is hard to remove, they sink their roots into the rock. Was it hard to remove?

If you're good at digging WWM (wet web media) is a great spot for pictures and information.

From the quarantine tank, when I moved I lost a huge hammer colony the skeleton did have several baby heads that survived. I have left the skeleton intact to allow them to grow. That sample came from one of the dead heads and a piece of the skeleton broke off with it

@Twillard I hate the format of wwm but will get the laptop out today to look through.

These rocks have been in a fish less tank for at least 6 weeks now. It does have lights but I've been running only the blue channel for 8 hours a day for the corals. And dosing at least 5 ml of h202 daily with very little die off, in a 10g tank

Thats a bad picture but it looks like its attached to the rock pretty well. Maybe it is and maybe there are different species of it. I cant answer for sure.

Yeah, not the best pic. My phone wasn't cooperating and I was rushed. I'm going to stop by work today and take some pics on the scope.

and some cool little creatures

Very cool!

Need to get his thread more attention so someone can analyze those photos!

Green turf algae or wiry turf algae.
I have a couple lovely tufs in my refugium.

The copepods seem to like it quite well

I do put it in the display from time to time.... "Auto feeder"

Bryopsis hypnoides i think

Bryopsis.

Ohh! I've had that.
One sprig. A friend told me to kill it, and I'm glad I did.

Does anyone know if h202 affects bryopsis and GHA differently? Recently read that h202 won't kill bryopsis, but it will whiten and shortly there after kill GHA; any truth to that? Just wondering if this would be an easy method to determine GHA from bryopsis.

No if you do the scrub and dip with peroxide it dies but will oft come back as the roots go deep.
But bry opsis I belive is feather leaf or something like that in Latin. So it's actually seen and named in the structure of the plant.
Gha is actually a constant mis diagnosis often as there hundreds of species that are incredibly similar. If you watch r2r threads you'll see this more and more. Many Gha are hairlike but many are branched and also fine haired. Two different species.
IMO peroxide will kill most algaes Esp thinnner skinned ones. Bryo like some turf algaes are just buried deeper in the rock and require rasping or nuking.

Gotcha, I have what I believe to be bryopsis, but no definitive proof. I have what I believe is GHA in my sump and its soft, when i pull it, it feels like it just rips off. The other stuff, maybe byropsis, is denser and when i pluck it off of frag plugs it doesn't seem like it pulls off but just breaks at the base; and since it always comes back, i'm assuming bryopsis. I've done pure h202 dips on the frags, which works, but eventually it always comes back.
