thanks for your help guys. i guess where i get lost is that water in, water out and co2...so what's the extra in or output for?? there's 4 in total...
and the valve is for control of the effluent is this correct?

Don't have a Reef Creations but often, water in and out, CO2 in, then CO2 recirculation.

Valve for effluent drip rate, seen posts where easier to control/adjust if on the output.
