What is the brownish stuff growing on the glass and decor of my aquarium?

The growth of brown diatomaceous algae and biofilm is a normal phase in a new aquarium. This will usually die off naturally and is later replaced by much slower growing green algae.  All of these are easily wiped from the glass using an algae magnet or algae pad. The addition of a small algae-eating fish, such as a bushy-nose plecostomus, can also help to keep algae growth in check.  In any case, algae growth will be significantly reduced once your plants are well established in the grow tray.
