Live rock turning green

[ryn_C_mu]

My live rock was white when I first put it in now it looks moldy is this ok

Moldy? It probably isn't mold, but algae. It's completely normal and will continue to grow until it is taken over by coralline algae (the pretty purple stuff). Your tank looks pretty new, you'll be seeing lots of weird things as the tank stabilizes.

can you post a clearer picture?

I'm almost 100% it's not mold, just the beginning of algae growth

Ya ok I will try and looking closely at it it looks in some areas a darker green... plant like which I assume is progressed algae

 

[ryn_C_mu]

here's the best I could do for better quality... What do you think

 

[George9]

Is it the white part? it kinda looks just like sand to me, is it fuzzy or furry?

 

[George9]

never mind I just read you meant the green part it's definitely algae and nothing to worry about at this point. Completely normal. Your parameters are probably off because the tank is cycling. You're going to see a few different types of algae as your tank matures, but eventually you'll want to balance light, phosphates and nitrates to keep algae away.

It's not sand soft of fuzzy its green same feeling as a normal rock

 

[ryn_C_mu]

Can sand get stuck to the rock it is live sand too

 

[ryn_C_mu]

Yah but the stuff that looks like sand the stuff you saw on the first picture

 

[George9]

Don't worry about it, it's algae, you're fine!!

It looks like what I just read a green coralline disease is that ok
