I guess it is my turn now since I have kept the same Caulerpa as you for many months (hell it came from my place right?) I have never had the "sexual experience :D . Chunks of the Caulerpa will go a transparent white. I just remove those pieces. I forgot to mention it, but it sounds like you are a prime candidate for some Diatomaceous Earth filtering. That stuff filters down to one micron. I used it successfully about 25 years ago. The Vortex filters are still available. They are expensive, so it might be an idea for the group to get together and buy one. Then when one of us has a problem they can use it. That is my idea.
