Hi all.
I have set up this new tank 4 weeks ago. I have put a piece of root in it from the start and today i noticed some white growth on it at the base. I'm sure it wasn't there a couple of days ago. I have attached a close up. Could anybody please give some guidance on what this is and if it is harmful to my tank population? Thanks
