I have a pure freedom set up with pre filters 40/40 filter and di vessel, I've only been going 8 months so still only doing 2-6 jobs a day, I changed the pre filters and resin 2 weeks ago and only filled my tank 2-3 times since yet the ppm has already risen from 0 to 6 I have flushed the tank and was told the 40/40 filter would last well over a year so I'm just unsure why the ppm has risen so much as last time I changed the resin it took about 2 months to get to 5ppm, any help greatly appreciated.
Thanks.
Thanks.
