Been tooling around trying find this stuff thought I'd stop in ask you guys. The bottom 2 are Caulerpa pretty sure the top 2 are of the same type brown leafy pretty stiff so I'm thinking it's calcifing. (spl?)

Found them!!

ReefCleaners.org | Clean Up Crews and Macro Algae - Nuisance Algae ID Guide

Description- Brown algae, has forked branches may have iridescent blue hue. Here is the thing with the dictyota sp. - there are tons and w/out a microscope the best you can get it down to is like a handful of different species. If it is a brown algae, with forked branches, is not rigid, it is probably dictyota. Some species of Dictyota are desirable, you will be able to recognize them as they grow as one plant that branches out from one distinct holdfast. Removal would be very simple. Nuisance species of Dictyota, (pretty much all the iridescent sp.) stay shorter and creep along the rock. Their branches form straight from the rock, and there is no trunk like feature to the algae, or easily discernible holdfast.
