Triple ID

Have a new tank (240) about 3 weeks old now, still in the cycle. Added about 5 lbs of LR approx 2 weeks ago and now I have the following stuff growing. Just looking to find out what it all is and if its ok. Click images to enlarge a bit more

First one is some green stringy branch type of object, no idea what it is, just noticed it today:




Second is some type of sponge:



Third is a coating of brown possible algae covering some of the rocks in the tank, not out of control, but don't want it to get that way either if its bad:



Thanks for the help as usual!

 

1st is probubly some type of caulpera or hair algae 2nd is a sponge its completly harmless so leave it in. 3rd is diatoms i think hope this helps.

 

First one looks like bryopsis. Get it out asap and get your eyes out for more. Very difficult to eradicate.

Second look like a sponge to me.

Third one is diatoms a natural part of the cycle. You will probably have hair algae problems after the diatoms disappear in the next week to month and a half.

 

recommendations on taking the "green thing" out?
