I just started a Red Sea Max 34 galons...saltwater, live rock (20 pounds), aragonite on October 12,. Everything looks good and clean ph 8.0 amonia 0, nitrite 0...after a couple days I saw a kind of feather dust, a very small snail etc...but last thursday/friday I notice the aragonite got hear and thear gold spots, and my live rock has been cover by that gold spots too. Sometimes even on the glass I can see those gold spots, with can easy been clean with a magnetic clean up tool...
So is that normal? Do I have to do anything about it? Am I doing anything wrong?
I have my lights on for 12 hours....
