HELP! Macroalgae ID

[searoyalwulf]

Hi, I think I have two types of Chaetomorpha, but I'm not really sure. One is like thick spaghetti while the other is very much thinner and is more tightly balled up. Have any of you seen this type before? Is it just another form of Chaeto or is it something else? Your help would be greatly appreciated

ooo, is the tightly balled stuff what I've seen advertised as "japanese" or "korean" algae?

Well, not that I am aware of. I purchased this stuff from LA Reefs on ebay. They just list it as Chaetomorpha.

My chaeto grows simply floating in the water, but I do have a larger size macro algae that grows on the rocks.
