Rgwiz11 Posted February 2, 2010 Share Posted February 2, 2010 Most likely it's a diatom bloom. Nothing major to worry about as most tanks will have them. This is especially true if you are just starting out and your tank is still cycling. How old is the tank? Quote Link to comment Share on other sites More sharing options...

NonSequitur Posted February 2, 2010 Share Posted February 2, 2010 Sounds like either diatoms or possibly the very beginnings of a cyanobacteria bloom. Have you tested your water parameters? Quote Link to comment Share on other sites More sharing options...
