Setup instructions are also included. Most calcium reactors are a guessing game on setting them up. No more guessing! Read the instructions and dial it in for your tank. I answer email questions within 24 hours of receiving them.

*Venturi inlet means there is only one pump needed!  The recirculation pump also will draw the water from the tank or sump to feed the reactor! 

NOTE - If you want to add a pH Controller - MAKE SURE you add the Probe Holder Upgrade
