RODI

[CopperFish]

I recently got my RODI water tested by ATI and the results are below. Asking for advice/insight on results as Silica, Zinc, and nutrients seem high. Should I add stages to my Spectrapure system? I currently have a 4 stage (pre, carbon, RO, and DI). If so what stages should I add?

Do you back flush your RODI before using it?
How many gallons have you run through your RODI since last changing filters?

Do you have an in-line dts meter?

Do you have an in-line dts meter?

Yes, and it’s reading 0 TDS after the DI filter.

If concerned Spectrapure has a silica busting cartridge.
You could add another canister with that in it.
But -0- is still what you want to see.

I think you should not spend money on RODI ICP tests.

I have well water from farming area. I simply replace dual membranes annual, and replace all resin semi annually. I run anionic resin first followed by dual mixed chambers, and run to 0 TDS outlet.

Always highly suspect ICP as near infotainment.

I get 0 TDS in estimated by a 0TDS with all fresh carbon and DI cartridges. I throw away the first 40 gallons out of ignorance as the "PRO" anionic resin smells like ammonia or amine.

When cartridges age I get a 4 TDS incoming to DI and 0 outcoming PPM tds

My worst reefing experience has been spent DI resin so I change it twice a year and RO membrane once a year. This is too often but I rather just be done withit.

Yikes I change my di resin cartridge every month or two my carbon every 3 months and membrane every 6 months. Maybe I change to much . My main water supply is around 50tds .
