Co2 problems. Leak?

[FishCr8zy]

So I got my co2 tank filled up today and when I set everything up, co2 only came out of the diffuser when the bubbles were at nearly 5 bubbles per second. That is a lot of co2. Now when I turn it down to 1-2 bps, nothing comes out of the diffuser. I am pretty sure its a leak but can't seem to find any place the co2 could escape. Are you supposed to silicone every place the co2 tubing is cut and linked to a check valve, bubble counter, etc?

I would use Teflon tape on the connection between the co2 tank and the regulator it comes off easy and creates an air tight seal.

What working pressure are you using?? I had my regulator set at 1.5bar pressure which was fine until i changed my diffuser. Ive had to up it to 3bar pressure and no get whatever bubble per second rate i want

Which gauge tells you what the pressure is?

On my regulator i have two gauges. One is a high pressure and tells me the cylinder pressure. The other is my working pressure. Take a photo of your regulator
