Thanks for the quick answers. I'll do a flush and move on to water only.

After a flush, would you suggest adding any calmag to the water?

What kind of meters do you suggest for pH along with ppm? I'm not familiar with the ppm measurement, I'll do some additional searches on that.

I'm a troubleshooter by trade, so I fully understand needing as much information as possible. Filling out the form made sense! I'm glad to have it available. Thanks for the kudos.
