Macro & Micronutrients

Do macro or micro nutrients affect kH and/or gH? i.e. - iron, manganese, boron, potassium, phosphate, etc. If so, which ones and how much based on your experience.

Thanks to Google, I found helpful sites explaining more about the relations between gH and kH... The fact is there is no real relationship, they are separate measures.


In general, are calcium and magnesium the elements responsible for gH, while carbonate and bicarbonates are responsible for kH?

I am looking for the white labcoat technical information about water parameters. Yes, I am an engineer, can't you tell?

i think you're right about what affects Gh and what affects Kh (remembers its Kh, not kH...but it is pH

dosing ferts shouldn't affect Gh or Kh to my knowledge, unless you're dosing calcium carbonate to raise Kh/increase calcium lvls...but that's obvious.
normally when dosing traces, you just aren't dosing enough to have an effect on Kh/Gh levels.

Head over to Seachems Article section:

They have several writeups there in PDF format, and a couple of them speak to the topics you are asking about. I think the very last article, "Understanding the General Chemistry of the Planted Aquarium" is what you'll really want to read, and "The Art and Science of Aquarium Management" also contains some information in that area too.
