Ok I found the page you referred me to and I'm not sure which ones they are. My question is, are they bad? Should I get rid of them and if so how?
Thanks

The 1st pic looks like Bryopsis plumosa.http://www.saltcorner.com/sections/.../guest/algaepage/Green/hairalgae/Bplumosa.htm

The 2nd photo looks like Valonia utriculosa.

There are not many hobbyists who would want either algae to proliferate in their display tank.

2nd one is some kind of bubble algae. Get an emerald crab.

The second pic i've had a piece thats grown about an inch, inch and a half aquare in about 6 months. And doesn't spread quick, so If ya wanna know the growth rate compared to other algae. I think it looks cool and its in a dark spot in the tank and out of the way so i could care less.

if you ever plan on getting a tank then it will mow it down in a sec. emeralds are good and will do the job but i have had them pick on corals

If you like it better than the coraline then keep it otherwise get rid of it since it will compete for nutrients.
