I use to buy water from a LFS and their TDs was 60. And they said that's strange we just changed it. It was the last time I did that. And thats where my algae bloom came from

Keep in mind most TDS meters do not compensate for temp. You should try to use the meter when the meter itself and the sample are between 70-75 deg F. I find I get the most accurate reading when using a clean glass container and keep the meter in the middle as far from the the bottom and sides of the vessel as possible. I have found with two of the meters I have that colder temperatures result in a lower reading with a difference of 6ppm. That a big difference when your trying to determine if its time to change the filters or RO membrane.
