Declining Mature SPS Tank

I would recalibrate everything. From controllers to testers. Then I would do a hard cleaning of my sump. That means draining and wet vac out and wipe down and inspect. This should cover most things by just going through this regimen.

Swings in parms for sps can sometimes cause issue. The phosphates didn't seem like big deal, but making sure your readings are correct by calibrating everything will ensure you are not chasing a ghost

I'm seeing the same thing with my icp test. Blue bucket has very little of the things the icp tests for. I'm getting zero readings of molybdenum iorn potassium manganese. But high in aluminum vanadium copper and other heavy metals . I stopped using the red sea trace colors. It has alot of heavy metals in it. I'm sorry to hear about your troubles. Hopefully you got a handle on it now.
