Need a Calcium Reactor and CO2 regulator for 120ga

[HarleyGuy]

Hi All,

I'm sick to death with trying to do 2 part or other options. :-) 

I need a Calcium Reactor, CO2 regulator, and possibly a CO2 tank (5 or 10). I want a setup that reliably works and that will be enough for a medium to heavy load 120 gal system. I have a lot of hardware to trade or purchase if the price is right (like a brand new Apex DOS and DDR).

I've looked at Aquarium Plant regulators, Geo and Korallin reactors. I was hoping that someone has spares of everything I need to put together a good Calcium reactor setup. Please let me know. 

thanks,
