Just been looking at JamesC's remineralising recipe on his site -
http://theplantedtank.co.uk/RO.htm
A few questions about it if anyone's able to help -
1. presumably when magnesium and calcium sulphate is sold it is usually in the heptahydrate and dihydrate forms?
2. why add chloride, why not have all your GH from sulphates?
3. presumably K2CO3 contributes twice as much alkalinity as KHCO3 for a given number of mmol?
4. where are good places to get potassium bicarbonate and calcium chloride from?
thanks very much, as always!
