Okay, update: it's that time of year again to replace my RO/DI cartridges. I have the BRS 5 stage unit. Been thinking of upgrading to their pro series by adding two more cartridges and resins, but I'm riding the fence on it. My mix bed resin lasts a great deal of time and actually out lasts my prefilter and carbon blocks. During their use, the resin burns about half way up in six months of use. Tds coming in is around 3 and out is always 0.
The thing that may concern me is silica. I'm concerned that it's bleeding out or through the mix bed. Going pro series may be way over kill.
So the other option would be as assurance would be adding a second mix bed cartridge. This would make it a 6 stage. I'm leaning towards this option.
No I haven't tested my water for silica or silicate, but every year around this time I get some diatoms in my system. I have read that some water treatment plants add silica to the water supply around this time of year to reduce corrosion in pipes and that it can slip past RO/DI units.
Your thoughts and input are appreciated.
