Welcome to 3Reef!!!
What you have is a phytoplankton bloom. The quickest way to get rid of it is to borrow or buy a UV Sterilizer.
The next best way is stop ALL light from entering the tank for numerous days. You can't even let ambient light enter the tank so tape black construction paper, carboard, etc to all of the glass surfaces and do water changes daily with a zero phosphorus salt mix and ro/di water.
No matter how you solve this problem, you need to figure out the fertilizer for the bloom. Do you have excessive phosphates or nitrates from overfeeding, not skimming enough, etc? Do you use RO/DI water? If you use crushed coral for substrate, do you vacuum it enough?
Alternatively, start selling your phytoplankton and use the money to set up a new tank. (just kidding)
