ID on Live Rock Growth - Remove rock?

[edluva]

Picked this rock up from Petco because of its color. Has been sitting in my 24Gal Nano for a year. Moved to a separate new 90Gal display tank but want to make sure it's ok. My question is - should I get rid of the piece of rock based on items below:
1 looks like red velvet algae. Doesnt seem to be cyano. Hasn't spread to any other rocks.
2 looks like a green wiry algae. Growth has been slow over the year.
3 looks like some type of coral. Doubled in size in a year.
4 looks like a sponge. At one point it had 1 or 2 openings and water was flowing out.

Tank parameters are normal. Have GFO running to keep phosphates down. Flow seems to be ok in this area. New tank is only 3months old with only some GSP, frogspawn, torch, zoas, and 2 clowns.

Let me know if you need more info.

Thanks for the quick response!

I believe (I have it too) that the 1 is Red Turf Algae. Will eventually spread, although very slowly.

2 Looks like some type of macro algae, doesn't appear to be harmful, at least not Bryopsis anyways.

2- Looks like it may be Ernodesmis Verticillata

BTW, I'd watch out on getting petco live rock or anything for that matter. Usually has some pretty nasty hitch hikers.

Thanks for all the input! Going to keep the rock in my DT for now. The rest of the rock was from reefcleaners.
