JBL ProFlora CO2--venttiilin solenoidiventtiili ohjaa luotettavasti CO2:n syöttöä akvaarioon. CO2-syötön voi katkaista yöllä valaistuksen kellokytkimellä tai yhdessä elektronisen ph-säätimen kanssa CO2-syöttöä voidaan muuttaa pH-tason mukaan.

My first solenoid valve was a JBL one and it has now worked 8 years without any problems. So when I needed a second solenoid valve I decided to go with JBL again although there would have been much cheaper options. The new solenoid valve has been working just as well as the old one. They don't get warm, they don't leak and they are silent (you only hear a quiet click sound when they turn on or off). This solenoid valve would deserve 5 stars but because of the high price I will only give it 4 stars. I think JBL should lower the price, then people would buy a lot more of these great solenoid valves.
