Makes no sense. Check these water perimeters!

Had big problems after a long trip come home to a nightmare. Since then my perimeters are up and down and especially the magnesium. Last week I turned off the doser for the pump that was adding the magnesium and it's up and down with no water changes?? How is this possible!

Also woke up to my blue tang dead!

Let’s see all your water parameters.

@Humblefish and @melypr1985 what you think on the tang.

I don't see any obvious diseases. I'm assuming the paleness is just post mortem decay?

Are you still dosing kh and cal? What are you using to measure the various parameters as it's not just the magnesium test that isn't stable, also what's your phos, nitrate etc levels like.
