Could be diatoms, too.

I know we had a problem with cyno we were told it was from over feeding by everyone and we weren't. One of the guys at big al's aquariums disscused everything to do with our tank and after a hour of showing position of rocks ,type of fish ,all the chemicals ,corals ,filteration ,he said it was due to not enough circulation in the tank

ok since I have limited the light for a few days it has decreased quite abit there is still some there but there is a big difference so what would it be now (cynano or diatoms )after no light for the last few days??????
It's not a new tank and I also cut down on some feeding
