Hi all
I am new to salt water aquariums and managed to get a fantastic set up for free. so off i went and got it sorted and filed with water to eventually add life to it.
whilst looking at it today to take some tests and record them to see how it is doing i saw life on the rocks, these rocks were in the tank with the last owner and only out of water for 3 days or so.
can anyone tell me what these are and what i have to do to them if they have to go
though my camera has issues as i broke the glass over the lens the nodules are a brown colour in the tank
