Hi i am new to this group. I have been suffering with dino for few months now. I thought I had defeated it but I think it is in my system still. Could anybody give me any guidance as to how and overcome this as I am on the verge of shutting down my tank and getting out of the hobby. Picture below is mt reefer 250, its not bad at the min but i get a brown film that covers mt wier and a brown film on my glass when i scrape.
Thanks guys
