reactors

[mark]

Need to drop the pH to dissolve the media but finding a reactor can be rather simple.

I picked up a second chamber to a DIY reactor, that I was going use for the tubing to make another Ca reactor. While trying to decide uni-seals or threaded fittings for the recir pump, I just hooked up my CO2 system.

As is, basically just a capped cylinder with feed water and CO2 tee'd together then fed to the bottom flowing up through the media then out the top back to the tank, easily keeps Ca and Alk up in a moderately stocked SPS 145g reef.
