[quote=Weedhound]Hi GB....Love your blue dobie. Isn't 356 gpm a water pump or am I mistaken?

Thu, post 18, second photo, lower right below drill bits next to grommets. 1/2 inch stop valve.


Um, I'm confused. I'm familiar with the valves. Those valves are 1/2" lines usually regulating water flow? How do you use them on the air pump nozzle which is tubing like for air stones, etc.? How do I know the flow is enough on the air pump when numbers stabilize?
