The back of my tank has established a pretty good growth of purple and green algae-tyep grwoths, along with some spotty gray-brown stuff. Somewhere along the way, I seem to recall someone stating that that is a healthy process in my tank as it matures. I should mention that I've had my tank almost one full year now, and it contains LR
, a clown, a goby, and firefish all healthy (although out of sight most of the day to my frustration). I do scrape the glass of any growth at least once per week, but the back glass has been left untouched.
Am I doing the right thing? Shouldn't the back get covered with growth eventually?
