Bryopsis??

Wrassenaround · Jan 20, 2022

Hello all, would this possibly be Bryopsis Algae? When I manually remove it, it grows back within a few days. If it is Bryopsis what would be the best way to get rid / control it? I've read that it is the some of the hardest types of algae to eradicate.

I don't see any bryopsis there. Bryopsis is fern like.

I'm pretty sure mine is byropsis..

Been battling this for some months now. I'm able to pick some of them out but they grow back in a week. I have a lawnmower blenny but he doesn't seem to touch this stuff. Also had an emerald crab that worked more what little GHA i had but she didn't really touch this stuff either. Are there any natural predators to this stuff? I'm afraid to use Reef Flux because of the possibility of losing some corals.

Definitely lettuce nudibranchs, supposedly emerald crabs.

I do not think that is bryopsis. As others have mentioned, it typically looks fern like. What makes it so hard to kill and get rid of is that it roots into the rocks

I do see that fen look in that last picture so I say it is bryopsis. I had awesome success with reef flux and no side affects at all

I had used Reef flux with hundreds of corals and no issue

Just recently battled bryopsis used Reef Flux it cleared up in 14 days, if you follow the directions correctly and don't over dose it works great all my Corals look perfect had no side effects what so ever.

They can be tough to find available but abalones are known to eat bryopsis(and most algaes). Have seen some say their abalone did not eat bryopsis but i always had good luck with them.

Make sure it is Haliotis asinina or another warmer water species if you go that route though.

Reef HD capsules or Blue Life Reef Flux?

They are the same thing. I used reef flux on my tank and reef hd on a store system (I think it was reef hd)

That is bryopsis. Reef Flux works and didn't have any effects on my coral. Just follow the instructions. I don't keep acro's, so if you do then maybe ask someone else, but no bad effects for me on my LSP, softies and a few easier SPS.
