Review on 🐠 FZONE DC CO2 Solenoid Valve: Ideal Magnetic Valve for Easy-to-Install Aquarium CO2 System Regulator and Optimal Water Plant Growth in Fish Tanks by Claire Soto

Revainrating 5 out of 5

CO2 solenoid valve for CO2 do-it-yourself systems.

I bought two such magnets from myself for two planted tanks. Both work perfectly. They get a little warm, but this is normal for the function of the valve (solenoid), they can still be touched with bare hands. My recommendation: Place it at least 12 inches above the homemade CO2 valve so the baking soda and citric acid mixture doesn't reach the valve lest it fail due to the hardened mixture inside the valve.

Pros
  • Everything is fine!
Cons
  • There are disadvantages
