Ended up dosing all affected macros in a 5 gallon pail, and isolating the refuge.
Completely drained the refuge, and scrubbed the walls with a vinegar bath. Added new salt water, replaced macros and added an ato the isolated refuge, will be leaving it offline for quite awhile.
Dosed the tank, just to be sure, then performed a 20 gallon water change after. Hopefully that should be the end of that story.
Thanks everyone
