I got an in-line diffuser and after all the faff of cutting tubes to install it and dealing with leaks itís finally up and running and Iím pretty disappointed with the results. I can see big bubbles coming out of the spray bar and straight to the surface, I thought online was supposed to be better?

Is this how itís supposed to look, anyone?

I'm pretty sure an Inline should reduce the amount of visible bubbles in comparison to an intank diffuser because the CO2 has more time to dissolve before it reaches the display. When I was running an inline diffuser though I found my tank looked like it was filled with sprite.

Maybe check if theres a recommended operating pressure? maybe your putting too much into it?

If your not happy with that inline option you could look at getting a prebuilt RG reactor, I think NilocG sells them on their site. Works inline with a canister, just a little bit larger

...if I take the dishwasher out and use paper plates I can put a tank in the kitchen without losing counter space

Yeah with a diffuser I don't think there should be any large bubbles that stay at the top. I use one through a Lily pipe and all the bubbles are very fine, and disperse through the tank well.

Check the operating pressure. Mine is 40psi, and it's pretty important to have it working right. Otherwise it could be the spray bar, or a defective diffuser

Are you using a reactor after the diffuser?

It’s this one
Atman External Efficient CO2... https://www.amazon.co.uk/dp/B07GVFRL...p_mob_ap_share
I’ve just got in the the return tube, what’s a reactor? It’s not working at all today, no bubbles in the bubble counter and there’s water in the co2 line, somethings def not right.

The 2HR Aquarist provides a good explanation of reactors and CO2 distribution. A reactor after the diffuser would help the CO2 bubbles dissolve into the water column before the water reaches the spray bar.
