treat bryopsis with macro algae

[dragonfisher33]

so somehow some way bryopsis was introduced into the refugium where i also have ogo and dragon's breath but it didn't spread into my display tank, most likely due to the fact that i have tangs and foxface.

i have removed ogo and dragon's breath when i used reef flux. during the treament, i also took the kessil H380 offline. the fluconzole did its job.

3 weeks later when every trace of bryopsis "appeared" to be gone, i put back the ogo and the dragon's breath along with the refugium light. lo and behold, the bryopsis came back. is there a way to treat bryposis without damaging/affecting these ornamental algae?

how do you go about in treating bryopsis that could be "hitchhiking" on the red ogo and dragon's breath?

You have to leave the macro in. Not all macro will die from flux rx. I believe caulerpa and some types of ulva are the most susceptible.

Fluconazole treatment does say to leave macros in. I have always left chaetomorpha in on treatments with no harmful effects. Other macros and caulerpas, I don’t really know.

I played around with reef-flux and macros a while back just to see what happened. Here is what I found and I should have documented it here, but it’s all in a note pad lol. This does not mean the stain of macro you have will do the same.

Thin string cheato (the light green really stringy stuff)- it melted

Thick cheato (dark green and thinker stuff) - it lived but lost some darkness.

Ulva (sea lettuce) - melted.

Red ogo- lived but turned a little more orange. Especially around the tips.

Spikey graciliria - no issues

Dragons breath - lost its dark color but rebounded fine.

Fern calurpa - browned out and melted

Grass calurpa - turned white, spawned and about didn’t make it. It did recover though.

Red Florida grass algae (long strand type of turf algae) - grew like a weed and didn’t care.

Grape calurpa - white grapes here and there, but those shed off and it lived.

All of this was done in a 100 gallon tub where I grow out macros. There was some bryopsis on a rock in a basket and it died and never came back.

Again, this was only one time as I was curious of what would do what with reef flux added. It is in no way a guarantee or was it ever repeated. I have been wantin log to do a more controlled test, but haven’t had time. Luckily all that died was just handfuls, as I had just setup my larger macro grow out and snagged some bits for messing around with.

I also assume the one that grew all crazy was from the spike in nutrients from the ones that melted. Nitrates stayed at 5 and then hit 10 after the cheato melted. Po4 went from .03 to .1 and then back down to .03 after a week or so. Nitrate also dropped back to normal after a week. The turf algae doubled in size in that time and I had to thin or up my dosing it to keep nutrients from bottoming out. I thinned it out and fed it to some tangs I had in qt lol.

Exactly what I needed to know! I just ordered some reef flux to deal with my bryopsis!

I have cheato, fireball and sea lettuce. When I get my reef flux in I’ll just dose my tank. If the lettuce dies oh well! I’ll pick up some more from a guy who grows it so well he gives it away.
