As a follow-up to my last post, the sites where I found this information contained some interesting notes. Many of them mentioned running a RDP (reverse daylight photoperiod), as a way to level off pH swings in a tank, and slow down the instances of sexual reproduction. They also mentioned running a 24/7 lighting setup which they claim keeps Caulerpa from going sexual.

Another site pointed to maintaining Iron (Fe) levels in the tank as a way to keep Caulerpa happy in a tank without it feeling the need to spread. Through non-scientific polling of users, they have determined that people maintaining Iron in their tanks were less likely to see blooms.

It appears as though there are more than a few ideas from folks out there like us.
