what type of water are you using?tap, ro, or rodi? are you skimming? we need to know more about your tank how long it has been set up ect. if it's a new tank then that is perfectly normal.

silicates are usually fuel diatom growth... If you have high levels of it then running carbon might help.

... and how old is the tank?
