Going throuh DI cartridge quick.

We aren't having any reports of faulty SilicaBusters, so I'd have to guess that you have a lot of CO2 in your water. We sell a CO2 test kit that will analyze the RO water (free of other tap water pollutants). All your other parameters are well within specs. Do you ever see 000 from the DI?

Sorry about the confusion. I have not purchased 3 this month. I purchased the 3rd canister for this unit, this month. The last one lasted 2 months and the first one lasted under 4 months.
