So im looking to controlle the drip rate on my cal rex and im just wondering what would be best something like

John Guest 1/4" x 1/4" Union Ball Valve - AquaCave

or

Regulation Valve, 1/4" (6mm)by AquaMedic - AquaCave

Take a look at these. Great all plastic needle valves I use three of them for my reactors.

I drip my top off water through a quarter inch line and a dial type valve from an air pump like the one in the link posted above.

I use a John Guest and it is a ***** to adjust. Once it is set and running then you don't have to worry, but getting it there.....

You can do it with the JG valve, but that is really more of an on/off type valve. Usable for gross adjustments at best, but not really made for precise flow control. The ones I posted are a nice balance between price and accuracy.

AND if you want to get REALLY organized, here is a link to a DIY reactor needle valve return manifold I just posted on my local club website:
