sera guide - Splendid plants in your aquarium

You can easily and precisely count the CO2 bubbles inserted in the reactor with the sera flore CO2 bubble counter made of high quality acrylic. A thin nozzle ensures clear separation of the CO2 bubbles. The sera CO2 solenoid valve is used be- tween the pressure reducer and the following CO2 devices for interrupting the CO2 supply automatically. The CO2 should be switched off at night, as the plants do not take up CO2 in the dark. They even produce CO2. The sera CO2 solenoid valve can be connected to every common timer. The most comfortable method: seramic pH Controller for automatic CO2 addition – micro processor controlled pH value adjust- ment by automatic CO2 fertilization. The sera pH measuring electrode included with the kit, monitors the pH value in the aquarium water. Deviations from the adjusted value are balanced automatically by CO2 additions. Among others, the kit includes the pH con- troller, the solenoid valve, test solutions and a non-return valve. The seramic pH Con- troller is easy to operate and can be inte- grated into every common CO2 fertilization system. It is also suited for effectively con- trolling calcium reactors and dosage pumps. 16
