Hi Trees thanks for the info .. the water tank usage is interesting, could be the lime in the cement lowering the PH.
Chlorophyll is something to also look into as it also alkalizes the body ( it also closely resembles our red blood cell haemoglobin ) .. It doesn't taste the best but worth a try and its cheap ! .. I take a shot every morning and feel generally better for it.
Cheers
