if bryopsis grows in sps frag would it kill an acropora?

[sensei]

I am a little confused of what is happening with some sps in my quarentine tank. they were happy but sudenly they started loosing color and polips have retracted a lot. I have not made changes in light, flow or feeding in tank

I just tested and parameters are:
kh:8.7
Cal: 510
Mag 1460
PO4: 0.04 ( hanna)
NO3: 2ppm

I noticed that bryopsis seems to be growing in some frags. I tried to remove it but if grows back. I am not sure if they produce some substances that can kill corals and this is why some of my acros are not doing well in my quarentine tank???

any ideas?

Not sure if bryopsis is like any others but I'm guessing they be me sucking nutrients up and causing no food for your sps.. try adding amino acids or some food source for them ?

Anything is possible but the strain of bryopsis that I have does not affect my SPS whatsoever.

Bryopsis has not taken oven the tank.
if it just growing in some plugs, but I noticed that the milli where it is growing is not doing well at all. There are enough nutrients in tank since PO4: 0.04 ( hanna), NO3: 2ppm. I also dose coral food 2 to 3 times a week in these tank. I am unsure if bryopsis produces toxic substances for sps.

Josh,
What are you doing to get rid of the bryopsis you have in your tank?
I have read that some people use H2 O2 and other higher Mag levels to 2000, but I am unsure if these methods would damage the sps in tank

Thanks

If the Bryopsis is brushing up against the coral all day and night, it can easily annoy the coral pretty badly, causing it to retract.

I'd suggest manually removing as much of the algae as you can.

bryopsis will eventually take over and can kill/choke out the coral. Even if you remove the visible bryopsis off the plug it will grow back. Low nutrients will not kill off the bryopsis, and there aren't many critters that will eat the stuff. My suggestion is to get rid of the bryopsis either by cutting the frag at good tissue and mounting on a fresh plug, or cutting the part of the plug off the algae is growing on if possible. Do not put any frag in the display that may have bryopsis on it. Bryopsis has been a never ending battle for me, I get close to eradicating it and it slowly grows back. Some say there are different strains, if you have the strain I do it's nothing to mess with.

As far as bryopsis affecting the whole tank, I would believe there is something else going on

I'm about to test a newer product called Vibrant, it's a dosing supplement that supposedly works on all algae, including dinos and cyanobacteria, it's reef safe and seems pretty simple to use. I'll be documenting my experience on my build thread in my signature, hopefully it works.

Toss a few lettuce nudibranch's in there and watch them eat it all up!

cprice,
have you had bryopsis?
did nudibrach ate it and never came back?
I ask becuase I know bryopsis has roots that get incrusted so even if you cut it, bryopsis grows back.

before I have tried using H2O2 on a piece of a rock were it grew and it worked great,never came back. The problem now is that it is in a plug beside coral so I can not use H2O2 with out damaging coral.

Thanks

fwiw, I added about 25 lettuce nudi's, they did eat the bryopsis. As the algae declined so did the nudi population. Bryopsis then came back after all the nudis died.

I will have to cut part of the plugs and some frags and put it in a new plug as you recommended. The good thing is that all frags are in a quarantine tank.

Thanks a lot.
