Diatoms and Cyano Bacteria

Now this is weird. In an established tank, I all of a sudden have red dust and red algae covering everything. I will be performing some water changes, but I have taken photos for those who are searching the net for examples.

  • First image with the green arrow is the Cyano Bacteria or red slimy algae as it is sometimes referred to.
  • Second image is the diatoms or the red/brown dust.

Both of these should not appear in an established tank! It should only occur during cycling.

A good article I ran across is here: http://www.nano-reef.com/forums/index.php?showtopic=132956
