Reef Fanatic CO2 Solenoid Valve & Korallin Brass Check Valve

Hi, I have a virtually new Reef Fanatic Solenoid valve, these go for $50 new and a Korallin Certified Check Valve that goes for $35 new, both are from my CA reactor setup that was not needed (run 24/7) for CO2 fine tuned. Take both for $35 shipped.
