Some junk algea

[802reef]

Hey all

I started up a new tank and some junk brown hair ( maybe ? ) algae came in on some of the new live rock. Tanks is about 2 months old.

What eats this junk ? How do I get rid of it ? Water quality is good - although there may have been some phosphates and or silicates in the water I used to set up the aquarium - I used tap water ( I know I know ) to set it up, I recently bought and set up an ro/di unit and have done 3 15 gallon water changes since then and of course all make up water is ro/di now.

What do y'all think ?

Thanks !

Can you get pics of it with more white light (less blue)?

 

[802reef]

Here are some I took a few weeks ago. Now
looking back at it I think the water changes and ro have helped. Better , maybe, but def not gone.

Based on the first pic (looking on my phone so hard to tell) it could be hair algae or Bryopsis. Any chance you can get a close up? If feathery looking it’s likely Bryopsis.

 

[802reef]

Hey all - so I found a spot in the tank where the algae has grown a little longer and it definitely has that feather look that you're talking about. So what is the usual approach to getting rid of bryopsis ?

 

[reefing102]

Nothing generally eats Bryopsis. I’ve had good luck with Fluconazole (reef flux) treating it. I know @griss has had success with it too

 

[griss]

Yep, Fluconazole will eliminate both Bryopsis and hair algae.

Fluconazole is safe for inverts and corals is what I'm reading - have either of you had any I'll effects from using it ? Even subtle effects ?

It melted some orange bambam zoanthids for me but everything else including other zoas was fine. It definitely was the fluconazole because I did 2 treatments a few months apart. Whatever zoas survived the first treatment got nuked the second time.

I had one Acro get burned but I think a chunk wasn’t dissolved and landed on it. Otherwise no ill effects.

 

[griss]

No ill effects for me at all. Acros, F. Ricordea, Zoas, Gorgs, etc and no issues.

 

[802reef]

So not to need an excessive amount of hand holding here - but how much fluconazole do I buy for one treatment ? Im not finding any info online thats making me feel confident im buying enough. I have a 90 gallon - between sump and rocks and main tank it's probably between 90-100 gallons of water.

Thanks !

20 mg / gallon

Bryopsis / Fluconazole

Anyone remember the dosage to treat Bryopsis with Flucon? I’m getting a little cropping up and want to treat. It’s been searching and finding conflicting things. It’s been a long time since I used it. I thought Habib posted a long time ago a conversion from mg to partial teaspoons or...

[reefing102]

Yep, if I recall correctly 20mg/gallon is what I dosed.

 

[802reef]

And you dose that what daily ? For how long? I'm not seeing any clear directions on Amazon where I'm trying to buy it.

 

[802reef]

This stuff yeah ?

It’s a one time dose. So at 100 gallons, you would need 2000 mg. The first few days there will generally be minimal notice of a change. Around day 4/5 you should start to notice some white tips forming. By day 14 it should be mostly if not all the way gone.

That’s the stuff I used. One thing I noticed in mine, though I didn’t weigh it, was the bottle was about half empty (still had plenty and I believe it was accurate as it appears I’d have 2-2.5 more doses). But that seems to be a common theme in the reviews.

 

[802reef]

Awesome thank you all- I know that was a lot of hand holding but I wanted to make sure I get this right.

Happy Memorial Day
