That's how they are set up in houses.. softener first then RO. The DI will give you maybe 1-2 ppm. Without it probably like 5-10ppm. It doesn't hurt to have the DI.

it will get filtered out, you might have to replace your cartridges more often though due to the increased sediment.

Yeah I just went ahead and got the DI my PPM without anything is 124.
It will be dam near 0 after the RO unit. A 4 stage should have a carbon, sediment micron and DI filter. Now make sure you follow the setup instructions and flush the carbon filter for 5 min THEN put the DI filter in and flush for another 20-30 min

Mines similiar =) no issues here
Difference is your is made up of various minerals. His minerals is are being exchanged for all sodium. Not good for plants

It's a cool topic to add.
Some waters have ppms that are not favorable.
Mine is beautiful in that it has all the good stuff plants love.
Most of my tap water comes from the rocky mountains.
The runoff collects all the good stuff along the way ending up cruising to cal. in the Colorado river.
Comes in at +/- 450 ppms and I cut it in half with ro as it has a lot of calcium.
My outdoor plants and house plants enjoy the tap water.
@Budzbuddha is your water from the Colorado river?
Yes I would say it's likely ok if it's 124ppm before the softener

I might have just wasted money on the RO filters
Cancel the order Amazon is good for that. I use tap also but I use RO in my humidifiers. If you use tap your asking for mineral deposits everywhere

I wish .... mine chimes in at 7.2 ph and 255ish ppm .... I still use it .... the arsenic , hobo jizz , decayed cats , benzene , research laboratory runoff , crusty condoms , diazinon , bifethrin , perfluoroctanesulfonic acid , perfluoroctylsulfonic acid and diarrhea makes my plants thrive. The age of clean water ANYWHERE IS OVER. Chromium 6 enhances the terp profile Lol.
Not necessarily... But if you can look up you local water report and tell me the total hardness I will have a better idea. Ppm wise it's fine but it may require a fair bit of acid. I'm about 95% sure it would be fine.

My tap is 7.8 and after running it through a Brita it's around 6. I mix in my nutes and it only goes down slightly. I can mix in some tap to bring it up where I need it. RO can be tricky to pH because you'd think pure water is 7 but RO and distilled especially like to absorb CO2 from the air, creating a weak carbonic acid which lowers the pH. I've let RO sit out for awhile and it got to around 5 pH.
Should be fine. You wanna stay under 50ppm sodium and the lower the better but I wouldn't hesitate to use it. The alkalinity is dam near perfect so you likely won't need to add any buffering to keep a stable ph. Chloramine is lower than most under 1ppm. 4ppm is the max so that's good. May want a bit of cal mag depending how much your base nutes contain. Copper is a bit high but not an issue.

Thanks man I'm going to return the RO
