Be careful with Caulerpa

hehehe.....

 

the light can do it to the algae, making it go sexual etc...also could have been dying if it was floating etc...It happens if it isn't regularly pruned too, and sometimes the nutrients just get to low to support it etc...plants and algae can die it happens...I am sure there is a pepper plant somewhere that has died, no reason to stop planting peppers.

But chaeto is definitely more stable than caulerpa. Good to hear you are getting good results with it.
