If I had a CO2 Regulator like yours, yes, I wouldn't be concern, but with my unstable Tunze, no way, It begin to fast bubbling (going from 3 bubbles per second to 30 overnight) when the CO2 tank has less than 30% of CO2.

I have never heard anybody complain about a Tunze regulator before. Are you sure that you are using it right, that it did not get water in it and is now unreliable from some internal rust (they do not come with solenoids so if a GOOD check valve was not used then this can happen) or that it is not a knockoff of some sort? This sounds like user error to me or else they would have a really bad rep like the regulator that comes with the CarbonDoser box, which is truly junk.
Tank pressure at 100% or 30% is the exact same. Exact. The pressure stays high as long as there is one tiny droplet of liquid co2 in that tank still. The only time the pressure changes is once all of the liquid co2 moves to gas form, but this is just a day or so before you are completely empty.
Run your reactor however you want. I just try and help people with what has worked for me over a few decades. Unfortunately, too much advice about how to use a CaRx is from people who have not even changed their media yet... or from vendors trying to sell you things. I get so many requests for help that I put together that document to help. Guess what... debris gets into the reactor no matter how you do it. Leaks will only happen if you set it up wrong or the seals are getting old - o-rings are cheap and easy if you plan ahead and replace them ever 8-10 years.

Thanks for the advice(s), probably the previous owner(s) didn't take care well of my Tunze CO Regulator or maybe because you use them 24x7 doesn't seem to be affected.
What I can tell you about check valves, I'm using a decent check valve (2 actually) one that comes with the bubble counter and a second one before the bubble counter.
I also have a Tunze solenoid, I bought it brand new but one of the plastic union pieces got broken so I had to replace them with coper ones.
Another question, do you recommend coper check valves on the co2 tubing?

Been using this DoubleSun regulator for a month and so far, so good. No issues, no leaks, nothing fishy except what's in the aquarium! Fits any standard C02 tank. Built in bubble counter is great (just needs a little water in it to work)
For anyone looking to get into C02, I would recommend this unit as your first regulator. It is relatively inexpensive compared to many high end models. You will need this, C02-grade tubing, a diffusor and a tank of C02. I bought the 3 parts needed and got the tank at a local beer shop. Total cost was under $200.
