Who’s up? Anyone? I have a macroalgae question.

[AydenLincoln]

I just learned of something I didn’t know and find horrifying that macroalgae (mainly caulerpa from what I read) can go sexual and asexual and basically release all the nutrients it stored back in the tank and cloud the water…potentially crashing it? How common or rare is this? I keep lots of marcoalgae in my one tank. I know there’s a million things that can crash a tank from an anemone to a dying fish and my blue sponge I have. But now I’m wondering/worrying at 2:30 am haha.

It's just a part of the caleurpa reproduction method. To minimise risk, prune/harvest often, and some say to run 24hr light.

prune your caulerpa, it usually happens if it's unhappy or if your caulerpa grows unregulated.

Thank you!

I've kept caulerpa for almost a year now with no problems but I now keep it under lights 24/7. Apparently if a chunk turns white it is about to go sexual (apparently in about a 24hrs) and you'll want to prune that bit off.

That’s dead macroalgae then and this has not been my experience lol.

Yes that can mean it's dead too. Here's my source. A great source for everything macroalagae.
