Ok I have had enough green water. Today I am totally blacking out my tank
for a couple of days and my question is this. Do I continue with co2
injection and running my filter while my tank is blacked out ?

If possible borrow or buy a UV Filter to put inline with your water
return. Run this for a few days to a week and see if the suspended algae
doesn't go away. The Polishing filter will work but can't rid you of all
of it for the long term
