regulator

Hmn. This is why I use the Azoo regulators, you only have one thing to open, the needle valve.

Have you tried opening the flow valve then tightening it to get the bps you're looking for? Seems like it would be a more steady release rate if it were stopped with tightened instead of loosened.

Yes, I think you are. While you are getting the regulator set correctly, remove the CO2 line from the reactor/diffuser and let is just sit in the water. That way, the bubbles will go straight to the surface and not lower your ph prematurely.

Continue using a tighten method to get your bps to your desired rate. It *will* take some time to get everything right... when I get a new reg, even the idiot-proof ones, it takes me around 48 hours to get the valve set correctly. You'll just need to tighten less and less to compensate for the bubbles tapering off after a few minutes. It just takes time.

Once you've got the right amount of bps, then you hook your CO2 line back up to the reactor/diffuser. You might want to consider getting a cheap bubble counter at your LFS, very handy device that.

That setup looks like its mising the needle valve.
I don't think its possible to get a good steady flow
using the regulator only.

Dur. My bad. it's been a loooooong Monday.

Most regulators don't come with a needle valve (unless you ordered one of those deluxe JBJ or Milwaukee setup), so you'll have to shop around for one. I had the hardest time finding one locally and just ordered it online from aquabotanic.
