live rock no coralline?

hey guys im curious, a friend of a friend is braking down there tank and going to sell me about 50-60 # of live rock throw in 2 star fish as well as 2 sea urchinsfor $50, my question is hes had the tank for 2 years with rock and everything has a professionaly set up system however i didnt really see any coralline growth on the rocks, he didnt have any corals but the tanks seemed to be in good shape other than the no real coraline growth should i buy or what?

 

Probably did not have the parameter in line that promote coralline growth.

If the rock is a good deal, and there are NO aiptasia, majano, flatworms on it then I would give a go.

 

+1 I agree. As long as you like the look of the rock and get it for a decent price I would say go for it

 

thanks guys yeah thats kinda what i was guessing hes got alot of live rock in the sump as well which im hoping he might throw in all in all the rock looks good has good size to it and should look great in my tank :-D

 

Don't take the urchins.... just the rock or any coralline you have on your present rocks will be licked clean too.

 

I have a Blue Tuexdo Sea Urchin who likes coralline, but it has not been a detriment to my coralline growth. As a matter of fact, I wish it would clean up more of it. My coralline was weak until I started dosing a combo of SeaChem Reef Buffer and Reef Builder - then it went wako.

 

Ya, some it it more than others.

I use Seacheam Reef Buffer in my top.... my coralline is crazy too.

 

He prob just ran a fish only tank, these do not need any real good lights to keep. So tank water may have been fine but may not have had light to grow coralline.

 

80% of my tanks are underlit and FOWLR. You don't need bright lights to grow coralline.

 

Its the sea urchin eating it. I have coralline all over my back glass and my rocks were becoming covered also, until I bought a blue tuxedo urchin. He has since stripped my rocks, but he is kinda cool so I don't mind. Doesn't really touch the stuff on the glass though.
