Water pressure 58 on gauge. 35 TDS going in 0 coming out. That’s with 2 RO filters to max output and min waste.

58 on the gauge is good. But it can be better.
You have 35 TDS going into your DI? That is way high. Mine was 8-10 before I installed the smart booster. Now its 4. It can go down to 3 when it run long enough.
Whats your tap TDS?
My tap is around 175-200

So far I’ve been using the same RO filter for a year now.

Now I am curious, 1 going in DI?Sorry - Tap water TDS is 35.

The 2 RO’s are connected back together again into DI before exiting to storage.

Very fortunate in NY - really high quality water and a tremendous supply of it (reservoirs everywhere just north of NYC).

I don't understand what are you stating here.
2 RO? You have 1 RO membrane.
What I am asking is what is showing for TDS before your DI stage since you have an inline TDS meter.
2 TDS?

My rodi system only shows TDS going into unit and coming out.

How do you like and do you recommend the smart buddy?BTW this is mine.
BRS 4 stages water saver plus with smart buddie booster

Is that how it's assembled by the manufacturer?
You don't need to know your source water TDS all the time. You need to know the TDS before going in DI, so you can know if the RO membrane need to be replaced
I do like it and recommended it. My only gripes with it, I can't adjust the the water pressure its being boosted. I probably need to open it up to do that. It's running at 100psi at this time.

Have 2 RO’s - here’s a better picture
4 Stage Value Plus 100GPD RO/DI System
Makes up to 100 Gallons of RODI Water Per Day! BRS 4 Stage Systems are perfect for reefers who have water treated with chlorine or relatively clean well water. Self-contained on a single bracket making them ideal for tight spaces or where a non-permanent connection may be required. Every BRS...

That's what you have, right?
Of course with the 2nd RO addition

Correct. Doubled output of rodi water and significantly reduces waste.4 Stage Value Plus 100GPD RO/DI System

Ok. My suggestion would be. Move the In TDS meter to the line before the DI
Guys - I zipped through this thread quickly - here's some feedback:
*Don't use GAC as a prefilter. Use a carbon block instead.
*Don't orient your DI filters horizontally. Always make them vertical with bottom up flow.
Some jargon:
*Resin that has both cation and anion beads is called MIXED BED (rather than dual bed)
*The clear vertical "filter holders" on systems used in this hobby are called HOUSINGS (rather than "canisters." And yes, I know one of the vendors in this hobby erroneously calls them canisters. Like fingernails on a chalkboard!)
One more thing:
On a typically configured RODI in this hobby (sediment filter-> carbon block->RO membrane->mixed bed DI; you'll want a THREE PROBE inline TDS meter
www.buckeyehydro.com
with probes on the feedwater, RO water, and DI water.
Add additional probes by adding 1, 2, or 3 probe meters as needed - you'll want a probe after each membrane, and after each DI stage.
