I switched regulators from an Aquatek to the Intense V3 (new version off of ebay) and now bubbles don't come out of the diffuser. I checked for leaks cleaned the diffuser and still no bubbles. When I hook up a cheap glass diffuser and open the valve all the way bubbles blast through, but when I do the same with the atomic nothing. I don't get it.
Here is a picture of the regulator. It is made by Naito precision, same as the diffuser so they should work together.
