Bryopsis in new tank, normal?

Dustinryan2010 · May 31, 2019

Been battling a little bit of Bryopsis and green hair algae here and there after cycling nothing too extreme. (Was overfeeding). I’ve been doing lots of water changes this week to get nutrients down even though they are testing 0, scrubbed the rocks and blew the Bryopsis off the sump glass, turned on my UV sterilizer and turned the lights down to 8 hours a day. While I know that nuisance algae is to be expected in a new tank (ugly stage), should I be concerned about the Bryopsis? I keep reading about how terrible and invasive it can be as it’s root systems are aggressive. Is it normal to see this during the ugly stage? Should it go away on its own or should I try some fluconazole? Not trying to rush the ugly stage at all, just don’t want my tank to be taken over by Bryopsis and I’m trying to get my nutrients in check. (Also using a skimmer and refugium running opposite of display). Also, what is this brown stuff on my back wall and return nozzles? Diatoms maybe? Seems to cover my filter socks too

Toss some fluconazole in there. I had bryopsis my second month in and it wiped it out. I spotted some again recently on a snail but I think it rode in on the shell. I scrubbed him and haven't seen any since but if I do see any more I'm treating again.

Second on fluconazole. I’d do it sooner rather than later to take care of the bryopsis before it gets out of control.

I know you will hate what I will say, but, If system is new and you do not have live stock, my advice is to take out the infected rocks and restart.
In my experince it will come back. No matter what you do it will come back. Since your system is new take advantage and just restart with better rocks or clean your rocks dry it and restart.

You must have got it from somewhere, it's not normal like green algae..this thing is evil and must have came to your system on a rock or something and infected the rest.

I’m going to try fluconazole before I go to the trouble of completely breaking it down, this stuff is all brand new dry rock that I paid a lot for. This got introduced to my system from a ball of “pest free” Cheato that I paid 30.00 for. Everything in this tank was dry/dead upon set up. I guess nothing really is “pest free”. ‍

My bryopsis and hydroids came in on chaeto as well. It was literally the ONLY thing I had added that was alive aside from “live sand” that had been bagged and boxed for a year.

The record I am not suggesting you break down things. I am suggesting taking all rocks out, clean, dry then put back. This is what I meant by restart.
If you started everything dry, then you should not have bryopsis...if its bryopsis it must have came to you from somewhere, bryopsis is not part of the cycle algaes...
Either way you go. Good luck and let us know how it goes.
