Check valves on a CO2 system?

Hi all

So, I've saved up the money for my pressurized CO2 system (Decided to go with GLA, hence the need to save...), but I have a question for anyone familiar with check valves on a CO2 setup, and, in particular the "Atomic CO2 Bubble Counter with Integrated Check Valve."

As the name states, the bubble counter has its own check valve built-in. Would it be silly of me to buy another inline check valve to insert between the bubble counter and the regulator as a backup? Would I be hurting CO2 flow doing that? Is the check valve on the bubble counter so reliable that it's not a worry?

Thanks much!

(Wasn't sure if this should go here or in the planted tank section, but, since it's hardware...)

I have an extra check valve on mine. I know it's over kill but it doesn't hurt. GLA sells a nice brass one but I just use a standard plastic one and relate it every 6 months because the CO2 makes the plastic brittle. It doesn't hut the CO2 injection levels.

Thanks for the advice, I appreciate it.

Is this the GLA check valve you were thinking of?
