Can somebody explain the relationship between GH, Calcium and Magnesium levels? If I know my GH, can I conclude what the ppm levels of Calcium and Magnesium are? My drop test tells me the tap water GH is 4.
I am using a KH+ product by Sera to boost the KH level (it is 1 in my tap water) - the list of ingredients tells me that it contains Potassium Hydrogene Carbonate and DI ('Aqua Purificate') only. I assume that this will help with my potassium fertilisation as well?
How do others in very low hardness areas, or those using RO, boost KH? Can I source KHCO3 myself and dilute it to make my own KH booster? Where from? I read in a aquarium water chemistry book that you could also use NaHCO3 for KH boosting, any advantages or disadvantages in this?
Thanks for any help - I gave up chemistry early in school so my knowledge in this area is a bit poor...
