Those look really like Dennerle and Bioplast type of one way valve.
Yup! Definitely a learning experience for me. I ended up not closing the needle valve enough overnight after fixing the system and came to office today to all my fish gasping at the surface as CO2 comes on 1 hour before I come to work (surprisingly the CRS were fine). And this is with the lily pipe lifted to encourage oxygen exchange overnight.
The boraras are fine now after I stopped the CO2 for an hour. Otos and cories still looking weak. I hope they recover

$2-$3 only, very cheap
I've read through the interesting thread and the points made are worth summarising.
Could I ask a few qn as I am going to set up CO2 soon:
(1) There has been discussion about inline needing high psi. How do I know if the equipment I'm buying will be able to deliver the psi needed for inline reactor if that is the best method? Or should most equipment be able to deliver the PSI needed?
(2) Does needing high psi for inline reactor translate to more CO2 delivered? I.e. inline reactor will be delivering a lot of Co2 to the tank, and not all tanks need that much Co2?
also recommendations of where to get full CO2 setup also appreciated. I just went East Ocean they got no stock...
It depends where you stay.
Nayang seaview (seletar farmway), NA (near thomson medical) provides one to one exchange to topup Co2 if you buy from them (it saves times and money as you do not have to go collect another day.
Bioplast(near boon keng mrt) provides sameday topup.
Clementi blk 328 local fish shop also sells co2.
And of course the buy and sell market at AQ will have people selling their 2nd hand set at a good price, just have to look out for it.

when you connect the regulator there are 2 indicator. One is for the tank the other is working pressure/pressure inside regulator.
Check with the LFS before you buy.
high psi does not directly translate to better co2 enrichment. (example you have high PSI but hook it to a simple diffuser@3bps)
These inline are much thicker and Co2 that can squeeze out are smaller, also harder and more air pressure require to squeeze them out.
Generally speaking, smaller bubbles seems to stay longer in water and better for enrichment.
Personal view is more surface area and stay longer in water, but some other views might differ thou we all think small bubbles are better.
Co2 set,You can see how fast you get back your tank (1hour or 2-3 days after) and where the LFS is. For drivers i see them preferring a personal aluminum tank & are stuck with BIOPLAST if they want on spot refill.
I am using NA myself, since i can just walk over and 1-1 exchange to a prefilled tank. (they still offer top up for personal tank but there is a wait time.)

When i have the time, i could summarise the thread. Info is in too many thread.

The info in the thread gave me the confidence to take the plunge to get CO2. Went to C328 and the uncle recommended Ocean Free Solenoid with screw in bubble counter/check valve. Seems to be a ok product. (annoyance was one of the required washers was tied together with the power cord - didn't notice and installed without the washer, hear hissing sound, and then found the washer... so far so good, but all this additional tubing, hope nothing comes loose...
For the diffuser, I believe its an Up-Aqua 'single sheath' inline diffuser. Seems ok but CO2 bublles do gather in the reactor after some time.
Congrats! Can go hi tech tank now. Since you got it from c328, maybe you can look for 2nd hand cylinders as backup, while you waiting for your topup.

think its the commonly found version . the one with 1 ceremic tube, most are the thinner tube.
reactor maybe mean the chamber where the tubes are housed.
Or perhaps he orthodox like i was haha...

Ans solenoid, with first generation up inline diffuser, been a year. So far so good, didn't experience with pressure issue. Even my ans indicator is showing 25 psi.
I stocked up 1 more diffuser, just in case it broke off
sorry Urban, probably my use of terminology is not precise. I am only using an Up-Aqua inline diffusor not reactor. It only has the small ceramic tube, whereas theres a twin version with both small and large tube. I followed the C328 uncle's recommendation and purchased the single small tube version.
I guess the next challenge is to ensure that the CO2 matches the lighting intensity or vice-versa...
folks who using the UP aqua new inline, need your info about which unit you buy and how are you using it.
I bought the double tube one, had a ton of problems when trying to hold everything nicely to get mist.
Now i am using only larger tube, able to get mist but got this feeling lose double tube abit. I already tuned down my BPS to desired level and just nice got some smaller mist.
Which combination you guys using.
@Urban, the seal when i used just the larger tube is much better. Not yet test smaller tube.

I guess it depends on the fitment of the ceramic tubes and rubber spacers within the individual units... because of the modular parts for ease of cleaning, there is a tendency for tiny gaps to appear whenever its taken apart and fixed back together, usually have to adjust until it gets a good seal.
@urban, think mine construction not so good. besides the finish around the o ring, i found when using just 1 tube the seal actually better & formed within 2hours a tight seal. when i used 2 tubes after 4 days no good seal.
ill try swapping the smaller tube after i got time. (confirm after my mom operation is done, right now no time) then i will post a update, if i can a video.

Maybe the variations in fit between the large and small ceramic tubes might be affecting how well it seals when both are installed (one might be just slightly longer than the other)... probably have to mix and match the parts to find the best fit.
the length of the tubes did came up to me as cause as well & finishing of the cover.
i still left some teflon tape inside to help the seal when i used the large one.
lots of thing can affect such a set which can take apart. maybe the 1st version which is sealed tight be better for not so tech folks.

I thought I should post my questions here rather to start up another new problem thread. After gathering the preferred choice for CO2 delivery system, I got myself the up aqua new "inline super diffuser" system (as per picture above shared by erwinx). Happily, I set it up to a second hand pressurized CO2 tank (with solenoid, dual gauges) which I bought in the Marketplace forum.
FYI, I am new to pressurized CO2 set-up. After turning on the CO2 cylinder, my working pressure reads 50psi and the cylinder pressure reads 900psi. And when I turn on the needle valve, my working pressure drops below 50psi. In general, when I increase the bps, the lower the working pressure. Therefore, I have to tune the bps release such that my working pressure hovers between 35-40psi. The up aqua inline diffuser requires at least 36psi to work. Is what I am experiencing normal? Is working pressure correlates to bps? Can I turn the CO2 cylinder to the max to increase my working pressure?
Next I notice there are no air bubbles visible in the diffuser chamber even after I left it on for >1 hr. I set the release at 2bps. Is this also to be expected?
