Due to illness have not been able to run merlin.for 2weeks.
This morning started producing water at about 75 ppm then after about half an hour it came down to about 12 to 13 ppm but would not go any lower. So i put it through the DI at that and produced 300 ltrs.Then when holding tank was full disconnected DI and checked ppm from merlin and is now reading 35 to 40 ppm ,merlin only been running for about 8 mnths producing about 300 ltrs aweek with an input of about 425 ppm .My normal reading has been about coming from merlin is usually 6 ,7,8 ppm .
