Never understood what they meant by ionic calcium. Just ignore that. Total calcium is low (if accurate).

The potassium, if real, is too low, but if this is AWT, they frequently seem to report it as low, and I'm not sure it always is.

The copper, if real, is on the high end. Do you use tap water?

 

[jam583]

Yes, it's AWT. My tank is fairly new, so I wanted a baseline (4 months old). I am going to start dosing KALK in my ato so that should help, I suspect.

I use RODI water I make and mix myself. Or, I buy the saltwater from my LFS. When tank was started, tap water (well) was used. I suspect copper might be remnants of that?

I would just ignore the AWT results, personally. There seem to be a lot of problems with their reports.

 

[Randy Holmes-Farley]

The copper (if accurate) might be from the well, yes.

 

[jam583]

Well, I read a lot of threads about the accuracy of these. Going into it, I realized many considered the results poor. The good news is, many of the measurements are aligned with what I had. I figured, if anything, this would be a baseline of sorts.
