[eksman]

Hello,

 

recently got into the hobby and so far so good. tank has fully cycled.

got a 96L ocean free AIO.

 

just wondering if anyone can tell me what the white stuff on the LR is and ifs something to worry about.

also on another pic, there are lots of scabs on the devil's hand coral, is it molting of what is happening to it.

thanks very much. really enjoyed reading this forum
