The arrow indicate the direction of air flow to your inline diffuser.

How should I connect the check valve?as I'm using inline diffuse connect to canister.the arrow point which direction?
The arrow indicate the direction of air flow to your inline diffuser.
So the arrow shall point to my bubble counter?or towards the canister.tks for the noob question
The arrow point towards bubble counter.
I though is another way round
Arrow pointing away from canister outlet, towards bubble counter

I am a little confused now.
I'm running the ANS bubble counter with inbuilt check valve, so I decided to add another brass check valve to be safe. Its the exact one that wst is using.
I set it up in the following manner:
Regulator connected to bubble counter ---> tubing ---> check valve ---> inline diffuser connected to lily pipe outlet.
My check valve is in direction of air flow, meaning the base of arrow is aligned towards bubble counter cum regulator and tip of arrow faces inline diffuser.
Maybe wst should let us know what kind of bubble counter he's using, it might be the same kind as mine.
Your setup is correct... most of us that use those metal bubble counters (which have inbuilt check valves) also use an additional check valve between the bubble counter and diffuser, this is for "double safety" and also to prevent tank water flowing back into the bubble counter (makes it dirty and algae starts growng inside the bubble counter).Originally Posted by mercur1al
When some people mention putting a check valve before the bubble counter, they are usually referring to those other types of bubble counters that don't have inbuilt check valves.
I'm using the ans bubble counter with check valve too.so having another check valve for safety purpose.
Thank you for your affirmation Idol!
I had half a thought to replace the metal bubble counter earlier as i remember one of the forumers advising against it as the check valve might fail suddenly. However, since i had done the leak test and was lazy to redo it, decided to leave it for now.
If so, the check valve should be placed somewhere between your bubble counter and the diffuser. Your setup is exactly like mine, using an inline diffuser. The additional check valve should be pointing in the direction of the Co2 flow, ie, away from the bubble counter.
Also bear in mind that the rubber o ring that came with the brass counter, which was initially fitted at the top, should be shifted to the bottom of the bubble counter, in between the regulator nipple and the bottom of the bubble counter.
Hi guys for those using inline diffuser can I know how u guys determine the co2 is inject into the water as we can't see any bubbles?
If you are using an inline diffuser, like the Up Aqua super diffuser or atomizer systems (which have ceramic tubes inside the unit), they will create tiny micro bubbles which look like mist. If the Co2 system and inline diffuser unit is working properly, you should see your whole tank have a misty look with lots of micro bubbles drifting around.
Ok thanks for the advice.worry that co2 is not properly inject

Hi hi guys it it correct way for the check valve?
The photo is cropped at the top and bottom so abit unclear, but assuming the Co2 tubing is coming out of the bubble counter and then curved downwards to the inline diffuser (somewhere outside of the photo), then the check valve direction is correct.
Yes the arrow is pointing toward the canister and the arrow base is at the bubble counter
