How often do I need to change the water / mineral mix in the testing bottles?
‘Mineral Test Kit’ will arrive all ‘ready to use’. The water in the kit has been filtered and had reverse osmosis to ensure that it is free of all contaminant. This means that this water and mineral mix will last for 6 months. Once you have used all of the water the kit came with or you have exceeded the 6 month time frame then replace using purified spring water, or distilled water. It is possible to use tap water, but it is less efficient, and do not mix with mineral water.
