We recommend you use distilled or purified water available from most chemists. Heat this water to boiling point (you must heat the water in a non metallic container, a glass saucepan or glass container in a microwave will do). Put your electrodes in by hooking them over the sides of the container, about 1cm apart, do not let them touch and then switch the unit on for 10 minutes. At this point you will have clear colloidal silver (3 to 5 ppm). If you carry on for about 20mins making sure the water remains hot (75C +) you will go on to produce yellow silver, a purer form.

The water has become too cold. Insulating your containing will help to keep the heat in.

It is just a matter of the size of the silver particles (Colloids) produced and their concentration. Roughly they are as follows. Clear = 3 to 5 ppm and yellow = 6 to 10 ppm.

The main side effect of too much silver in your system is a condition called agaria, where the skin takes on a blue/grey colour, which would result from about 50g of silver being taken. To make matters simple, a pair of our 80mm 99.99% pure silver electrodes weighs only 1.5g. You will consume about 90 mg of silver every day in your ordinary food. A typical glass of colloidal silver made to a strength of 10ppm (i.e. yellow) contains 5mg in the whole glass which is less than a tenth of your normal silver intake! So you can see it is incredibly safe.

YES, it can not distinguish. So we recommend you take and acidophillus supplement regularly.

When the device is used the battery is drained and therefore the battery test circuit will start to light up. When it comes on quite brightly from the beginning it is time to change the battery. You will also start to notice it will take longer to produce the silver.

This is quite normal, as this electrode produces bubbles of oxygen which oxidise the silver and make it become black. You should clean the electrode with a plastic scourer and swap them around.
