I have been reading about calcium scaling on the forum and other places, but here (this area or surroundings) it is very difficult to find anything related to the Calcium Hardness indicator.. (chemicals to balance this)..
Does anyone know any other chemicals/products that will help raising or reducing the CH indicator?
- Calcium chloride or calcium chloride dihydrate (how are this sold under commercial use, if any? (increase CH)
- Only replacing water is the way to reduce CH?
