So i am in the process of adding a co2 set up to my 7.5g nano tank.
I love the idea of having all the equipment underneath the tank so I will be running a canister filter with a paintball co2 set up WITH a must have dual stage regulator (thank you forum people)
MY QUESTION:
I really would love to have an inline diffuser to fit the theme of minimal equipment in the tank, however, after research i found out that inline diffusers need a minimum of 30psi working pressure. I know nothing about co2 at this point, would i be able to attain this “30 psi working pressure” if i am trying to get maybe 1 bubble per second into my tank?
Would a reactor be better for less pressure?
Also would really love to know what brands you guys use for inline diffusers. Hopefully a nano tank specialist can help me!

You can have high pressure with low flow. basically, regardless of how slow the gas is flowing, pressure will build up downstream of the regulator until 1 of two things happen... Either the diffuser allows gas through, or the pressure setting of the regulator is reached. As long as you can set the pressure to 30+ on your regulator, then you'll be fine.

Basically you need a minimum pressure to get the inline diffuser "atomizer" to generate small bubbles or "mist" shooting out. Too low pressure, and you just get big blobs of CO2 coming out. How that translates into bubbles per second depends on the particular diffuser, obviously the higher the pressure the more CO2 will go into the tank.

That said, I am not a big fan of (plastic) inline diffusers, ever since I had one disintegrating on me, luckily I was right there so disaster was avoided. But the thought of (in that case) 250 gallons of water getting evenly distributed on my hardwood floors has ever since made me shy away.

You mention you will have a canister filter on that tank. Some of them can actually act as a big reactor, and without much fuss or noise dissolve regular CO2 bubbles (which can go into the filter inlet). Others burp and airlock... so it just depends.

The thing is, even the top of the line GLA aluminum inline diffusers need 30 psi of co2 pressure to work,
I guess my new question would be:
Is there any way i can inject co2 into a nano tank that is not in tank diffusion?
Thanks for the replies guys!

If you are using a canister filter or willing to put a pump inside your tank (defeating the purpose of minimal equipment) you can always run a reactor which is definitely less pressure then an atomizer.

thank you appreciate the response. Was really looking at inline reactors since I will get a nice display stand and can hopefully shove all the equipment underneath the tank.
what do you think of this thing?

Bad quality image sorry but this would work for low pressurized co2, no?

Its using a ceramic disc (that white thing in the middle) to atomize the co2 the same as any inline or in tank system, so no this won't be low pressure.

A reactor is low pressure and definitely can get shoved under the cabinet. I am doing this right now in fact with my high tech newt tank. The reactor is being run from the output of the canister filter. Look into rex griggs reactors. You can build one just 12 inches tall for this size tank.

would love to build a rex griggs reactor. I just searched everything about it, seems legit. The only problem is ive never built anything before lol. Thanks for your thoughts!
