View Full Version : C02 in ro/di water

01/15/2017, 01:08 PM
I have a community well for water n have been burning thru di cartridges. I ordered a c02 test kit from spectrapure n my test results are 50 ppm. What is a acceptable range for co2 ? I'm assuming it's the lower the better. I'm gonna try areating the water n see how much it comes down.

That is terrible! 50 ppm of CO2 is as bad or worse than 50 ppm of TDS.

De-gassing the RO water before you push it through the DI section is the only way to beat it.

A good de-gassing should bring it down to 5 ppm.
