Need a Needle Valve - Where to get it?

[JRod]

I have a calcium reactor that I just can't seem to dial in. I turn the needle wheel down and if it is too low, it shuts off. I have shut down the CO2 and run it straight through to clear it out then turned CO2 back on, gives me a drop a second for like two days and shuts down. I need to replace the needle valve with a much better one. Can anyone point me in a direction as to where to get one. I am short of throwing this Reactor out the window. Thanks.

Try running more effluent out of the reactor, than raise the ph in the reactor to compensate. I like running my effluent like a broken stream rather than drips.
GEO sale's those micro ball valves that work pretty good.
