I might as well ask first...water parameters, tank size, and fish stocking level.
Can you provide a pic?

Most likely cyanobacteria: This is controlled by reducing lighting time, Using RO/DI water, controlling phosphates=Controlling feeding(cut down), Keep you nitates down by regular water changes, Good clean-up crew, and Protein skimmer!

Syphon out as much as you can during water changes.

Cyanobacteria is photosynthetic... But dont reduce your lighting. It thrives in low light conditions. Poor lighting can contribute to cyano. - everything they said needs to be addressed except for lighting. I've talked to a guy that increased his lighting on one side of his tank and it made that side clear up.
