I'd just work on the slime once a week, at this point. I would drop the water change schedule to 10% every other week. New salt can add nutrients (ammonia) to the system.
How much GFO is in the system and how often is it replaced?

I picked up a Hanna pho tester, I'm going to test my RO water then also the water after it's been sitting in my holding barrels. Maybe they are leaching pho into the water.
I'm running about 1.5 cups of GFO, changing once a month.
