Grape Caulerpa is similar to chaetomorpha & is ideal for refugiums copepods & rotifers
Caulerpa is a fast growing attractive algae of which there are many variations with leaves that look like ferns, grapes, etc. Not surprisingly, the different types are named after the look of their leaves. All grow rapidly by sending out runners which are held in place by root like holdfasts.
Good or Bad?:
Caulerpa is generally considered good when it stays where it is suppose too, but it can easily become a weed that can be difficult to eradicate in the reef tank. If you introduce Caulerpa into your main tank, either on purpose or accident, keep a close eye on it and prune heavily to keep it in check.
This is obviously only an option when the algae is housed in a refugia or sump. Herbivorous fish like tangs will help to keep the Caulerpa in check.
Caulerpa growth seems to be best under medium to high intensity, low color temperature lighting. Inexpensive Mercury Vapor or outdoor PC lighting works well when trying to maximize the growth of Caulerpa for filters or refugia. It will even grow vigorously under normal incandescent lighting
