It’s nice to see someone else who has gone overboard with their apartment nano tank. I really like my trigger Crystal ato container. It is nice to see the level, It looks great in the open in my apartment as well.

Wow 700+ TDS to start with! Gonna give that RODI unit a workout. Ultimately will be good investment for your tank.

Update 5/31/2019
My calium uptake on my tank was more than my weekly water changes could keep up with.
Took a trip down to my LFS to check out my options between a standalone doser for Calc or a Kalk stirrer.
My LFS had been testing out the X1 micro pump and I played with it for a while. It's small, modular with it's rotatable head and can be programed with a phone.
I still haven't decided on an aquarium controller and I'm probably 6+ months out before I buy one so this small single unit for $59 was a no brainer.
Once home 1 drilled a hole into my calcium bottle and added a 1/4 bulkhead. Calibrated the pump and now have it set to dose 20ml across 12 doses throughout the day. So far it's working for it's intended purpose and later when I get a controller and accompanying doser I could repurpose this one for one of my fresh water tanks or have it dose Trace minerals.
Yeah. I've been running the triple DI now for about 2 months and I've been needed to replace my DI resin at least once a month with as much water as I go through. And sediment filters are replaced every two weeks.
Water from the tap.
Post RO water
Post Triple DI Water
My alkalinity has been stable. never goes under 9.6 towards the end of the week prior to water change and sits around 10.4 post water change. My calcium however drops to the low 300s when it starts off around 410 after water changes. Hence the reason why I only dose Cal and not traditional 2 part or Kalk as those would make my already high Alk even higher.Normally you would want to dose Alk and Cal in equal amounts so that the ratios don't get skewed. This can be done by adding kalk to your top off water or dosing 2 part with 2 pumps, one pump for Alk and one pump for Cal.
Mine has always been over 700, I guess that's just Avondale water for you. I've already refilled the Canisters multiple times. I have had the system since December and added the triple DI and second RO membrane in March. Also I feel you may be confused with what is what. DI resin isn't its own thing. Cation and Anion are DeIonizing (DI) Resins. What you're referring to as DI after your Anion is actually a mixed DI resin that is both cation and Anion mixed into one canister.My water TDS runs between 650-700 during the summer months. Since you have the 3 post canisters, use the Cation, Anion and DI resins in that order. Since switching to that combination of resins my Anion resin is getting close to needing replacement, and that is after around 3,000 gallons of RO water. The Cation and DI resins are still pristine. I was burning through just DI resin really fast, not anymore. Word of caution, the Anion resin smells really bad, I mean really bad. When you change it, do it outside especially since you are in an apartment. I didn't know this and did it in my house. It gave my wife an incredible migraine for hours and I needed to open all the windows to get the stink out of the house.
It was originally a single membrane unit and post RO would be in the low 40s for it. When you add a second membrane TDS always goes up but waste water goes down. Right now I'm at a 1:1 clean to waste ratio. Everything is seated properly and fully sealed.Also your post RO water TDS looks way to high. My post RO is only around 11. I would expect yours to be around 15. Did you upgrade to the dual RO membranes or did the unit come that way? Also you may want to reseat your RO membranes to make sure they are in tight and sealed.
Nice setup!
