Just happened to notice this stuff in my tank. Can't get a great picture but hopefully it's enough. It's kind of bristley looking

That's strange looking. Perhaps some pics under white lights?

 

[Dmac]

Hope that helps

I wonder if it's the same stuff in my sump

I think so, but I can't tell how much of it is lighting

Same. LOL. I was thinking bryopsis but now I'm not sure.

 

[Dmac]

I googled bryopsis pictures and I think that may be it. I'll try to pull some out

 

[Dmac]

I tried to take some better pics. When I tried to pull it off it just kind of disintegrates. It's not like hair algae where you can pull it off in clumps.

looks like turf algae or bryopsis.

 

[Dmac]

Flucanazole?

Flucanazole. I zoomed on the picture ending in 150015 and it sure is bryopsis. It's growing in such an odd place that it looks really strange but if you zoom in, you an really tell. Sometimes the center stalk in bryopsis will almost look teal and that's what really threw me off when you posted the first two pic.

Thanks guys. I got to go back to doing a better job of cleaning off frags before I put them in my tank

I had some success on bryopsis control by increasing Mg to the 2000 ppm range. It did not eliminate it, but over about 1 month it decreased over 90% to a non problem level. It is still on a decline. I began my tank with live rock that had been aquacultured in the open ocean in Florida, so I began with many pests. I did not have much success controlling the bryopsis with vibrant.

I’ve been told by a field tech that every tank benefits from adding Magnesium, so there may be a good bit of truth in your treatment.
