That's an very old unit. But change out the filters and RO membrane/housing and you will be in business
>Question: what is the horizontal canister? It looks sealed...
It's an sealed RO membrane.
Upgrade it to this

Also jump onto BRS and buy the 4 stage filter kit. It will include a sediment and carbon filter and more DI
Either way.....that RO membrane needs replacing. I change mine every 2 years. And pick up a dual or triple in line TDS meter to monitor the RO membrane output and DI stage output.
Total cost will run ya $70. (Wich your still under total cost of a new unit)
Personally I would call BRS and get the RO unit from the 5 stage (without DI cartridge) and turn your spectrapure into a triple DI stage

Here's my setup. I'm on well water with TDS from 750 to 850 and ALOT of C02, so it's ALOT of stages
> I just changed it out because it was mostly tan and I packed it in tight
I assume you're referring to the color-changing DI resin?
Do you backflush your RO membrane? If you're having any issues with your membrane, replace it with a filmtec. They have the best rejection rate and [actual] gpd.
All that said, 1ppm could be chalked up to the margin of error of your meter. I wouldn't sweat it.
