halimeda crash?

[CWeed]

I've kept a large bunch of halimeda in my 55g for about 3 months then overnight it all turned white. Looks weird. Im gonna remove
it but has anyone seen this happen before?

Other macros been in tank for years no problem

happened to me when I started a UV sterilizer on the tank, perhaps because of lack of nutrients

I've read somewhere that certain algae will crash after undergoing sexual reproduction. What brings on the sexual reproduction ( many alga normally reproduce via asexual reproduction ) can be many things.

did yours all crash at once? I dont think theres a lack of nutrients in my tank (although I wish there was).

Could be. I got some red leafy algae (looks like kelp) that does that. buds form on the leaves then the leaf turn yellowish green and the buds pop off. But usually it's just a few leaves. This whole thing went starch white.

What your red algae does sounds more like asexual reproduction.
