How do I fix the TDS? Do I service it? I have had it for maybe 6 months. Do I do a specific thing like carbon or all of them?

Replace them all. That's high TDS going in. You won't need to replace the membrane, but the rest of them for sure.

When new, did your rodi system take your tds down to zero? I replace my sediment, carbon and di resin every six months.

When you get 5ppm from a 370ppm start, this means DI resin is exhausted, is not the last stage, or the water is passing by the media instead of through the media.

Why not just replace the resin that’s shot?
Do you know how to open these kind I have the tool for the other main ones does it work on this??? My resin looks brown like you said could be bad.

Not familiar with that type, doesn’t the cap screw off?
I thought so but feels really tight. I ordered some resin to put in maybe upgrade to bigger ones so they last longer.

Wrap a rubber glove around it or use a strap wrench. Those ribs are there to be grabbed by a specialty wrench, if you have one that fits go ahead.

It's leaking tds anyway, if you break it while trying to open it so what, if you don't try it's garbage anyway

6 months every cartridge is changed

Every like 200 gallons for me the di resin goes in the trash.

You cannot skip on water quality. This is a big priority in the hobby. 0 TDS is key
