Its the red stick like looking things they are hard to the touch, and under halides it was a huge mass and the arms criss crossed over eachother, under pc it doesnt grow very well.

The first 2 pics are Codium, 3rd pic is likely to be Porphyra, and 4th pic not sure maybe Scinaia.

the first two ids seem dead on but the third I have also had that kind before but this one i have now is not the same its really hard to the touch and its like individual hallow stems. I think it might be calcerous though im not sure. Are most hard algaes calcium based?

 

[graveyardworm]

Not sure about hard being a rule that the algae is calcearous. Codium BTW is a calcearous algae. I've got one very similar to the last one pictured, and so far no positive id. I call it red branching, maybe scinaia. Close enough. There are alot of very similar reds which can be very difficult to distinguish from one another.

I'm also curious as to what these two are called and they look sort of similar to your dilemma. Both seem to be calcareous. I think the second is a type of Dictyota. I've no idea what the first one is. It is very small and wire-like. I know the brown alga in the first is the beginning of sargassum. The fourth one of yours, does it look like this...

or this...

?

I also have some codium, and it is awesome. Mine has started to grow holdfasts--at least I think so, it's bound to the rock now--and a part of the original piece you see I broke off. I put it in a different area in my tank and it is growing as well! Happy, happy, joy, joy! Down with caulerpa (BORING), up with calcareous algaes!

Hope that helps some.
