Injecting CO2 without micro bubbles everywhere in your tank

[fish4phil]

Is there a way to inject pressurized CO2 into your tank without the little micro bubbles everywhere (while keeping it quiet)? Currently I'm using an in-tank glass diffuser, placed under my filter outlet, but small bubbles are everywhere in the tank.

I'm considering this Up Aqua brand in-line atomizer, though does this output a lot of little bubbles?

The Ista Turbo looks good too

The Ista External Ceramic Reactor Diffuser looks ok too, but oh, it leaks evidently (from a youtube review)

So, is there a way to inject pressurized CO2 into your tank without the little micro bubbles everywhere, and while keeping the process quiet like a glass diffuser?

A reactor is what you are going to want to shoot for to cut down on visible CO2 in the water column. There are a few DIY plans online you can follow if you do not want to buy something premade. An inline diffuser may help a little but without a large chamber to mix in bubbles will still be visible.

Would the Up Aqua Inline Atomizer work better, or the Ista Max Mix?

I have a gla inline diffuser which is identical to the up aqua and I still have visual bubbles in my tank. The insta mix looks like a better option to me.
