Probably you’ve got an overgrowth of diatoms or a brown algae. Compare what you’ve got with the photo a short way down this page: http://www.wetwebmedia.com/brownalgcontfaqs.htm
You can get some of the info from following the discussion in the forum, but if this is a diatom bloom, it shows a higher level of silicates in your tank. Some diatom bloom is normal and will disappear as the tank matures, but if the problem is within your water source or salt mix, it will continue. You can also control this through water changes or a protein skimmer (reduces the nutrients on which they feed), lighting (turn off lights unless you’ve got macroalgaes you want to survive), and circulation (increase it by using powerheads). A good cleanup crew (hermits, snails, others) may also eat some of this. If you can identify this as a diatom or a particular brown algae from this link: http://saltcorner.com/sections/guest/algaepage/algaepage.htm use the number next to name for your algae to locate an organism at the bottom of the page which will eat that.
