Hi,
I just got my Co2 system working yesterday. I went to Clippard which is located in my area, Cincinnati. The tech person there gave me a baggie of different adapters for the MNV 4K2 needle valve which has a tiny 10-32 thread on it. I got it hooked up to the regulator. I previously tried using a bigger model by clippard which did not have the fine control I needed. This needle valve is better but I am still not entirely happy, I think it will work though. I have read the system takes a while to stabilize. Is it normal for the working pressure on the regulator gauge to fluctuate by about 5 psi. It slowly drops from about 20 to 15 psi and then jumps back up to 20. It does the same thing whether it is set low around 0 psi or high around 40 or 50 psi. This also happened with the other needle valve and affects the bubble rate which is higher at the peak and lower whent he psi drops.
Also, anyone know if the configuration matters such as how much the main knob on the tank is turned which seems to have zero effect on my pressure, how much the knob is turned on my regulator, and how much the needle valve is turned. I have read 15 - 20 psi working pressure but not sure what the reason is behind that.
My Rena XP 2 filter intake has a screw on knob to prime the filter. Is running my bubbles straight into the intake going to let any of the bubbles escape where the air is at the top of the intake or will the bubble go with the flow of water? I don't see any bubbles come out of the spray bar unless I turn the Co2 up pretty high.
