sounds like an agae bloom. how much and how often do you feed? have you tested for phosfates?

a uv sterilizer would help.

whats your photo period (how long)? andare you getting direct sunlight into the tank and check for nitrates...
Phosphates isnt the cause

Algae bloom from the light and window. Cut lights down to 4 hours a day for a week or two.

Drape or shade for window will help.

20% water changes each week till clear

Run Carbon in the filter.

what PRD said....good advice there,
pass on the Phosreactor, as IMO you dont have a phosphate issue....just that darn window.
