if you tank in new, most likely diatoms, don't worry part of the process of cycling. Just keep water changes going and if you have a skimmer make sure it is setup correctly and skimming.

How long has your tank been up and running?
about 45 days, i was thinking that it might be my lightiing.
have you tested your water? your cycle should be way over but??? Depends on what you have put/added to your tank. Include your parameters, all equipment and any fish and the timing in which you added them.
