I started a compost using materials I have discovered are okay. Problem is I also put in some moss from the yard that was treated (turned black & brown). Will this ruin my compost or is there something I can add to fix it?
Moss killer dissapates quickly and doesn't kill grass or broadleaf weeds. If you want to go organic, make peace with your mossy lawn :). A dose of dolomitic limestone 2 times a year over several years will alter the ph of your lawn and sweeten it so that the moss will go away.
