Description

The AquaCare CO2-Reactor 50 is suitable for aquariums with a volume of up to 1.000 liters and is designed to be mounted inconspicuously in between the filter and the outlet. Due to the innovative procedure completley without a diffusion membrane the water is enriched with CO2 during the flow. In this way, the CO2 is simply distributed optimally throughout the aquarium via the filter circuit. Inside the reactor is a trickle material in which the CO2 flowing, coming from the pressure bottle, collides several times and is thus divided into the finest bubbles. The desired CO2-concentration of the water is reached before it enters the aquarium.

Through the transparent housing, the number of bubbles fed from the CO2-source can be read easily without the need for an external bubble counter. In addition, thanks to the absence of a membrane, the reactor does not require regular cleaning and maintenance and it operates nearly noisless.

To control the CO2-concentration in the aquarium, a drop checker is recommended. Furthermore, the upstream CO2-system should be protected from backflowing water with an appropriate check valve.

The reactor is capable of handling a waterflow of up to 400 l/h. If the filter pump has a flow rate much higher than 400 l/h, it is recommended to connect the AquaCare Bypass CO2 Reactor 50 mm.

The CO2-reactor can also be used for saltwater aquariums. However, it is recommended to use it only in nitrogen and phosphate limited marine tanks and to perform a consistent pH-control.

The various pre-installed grommets allow easy integration into an already established filter circuit. The universal grommets d12, d16 and d20 are suitable for hoses with the corresponding inner diameter (12, 16, 20 mm). The Eheim grommets are additionally equipped with a PVC union nut and are also suitable for 12 or 16 mm hoses.

Note

The pH-value of the water should be checked regularly (continuously for saltwater tanks) when using the CO2-reactor.
To protect the CO2-system a suitable check valve should be added in the circuit.
The AquaCare CO2-reactor must only be operated upright.

Hello! Can I use the reactor on my Eheim prof 4 250 without a bypass?

The AquaCare CO2-Reactor 50 is designed for a maximum flow of 400 liters per hour (l/h). Since the Eheim professionel 4 250 external filter has a pump capacity of 950 l/h, it clearly exceeds this recommendation. In such cases it is recommended to run the reactor with a bypass to reduce the water flow through the reactor and ensure optimal CO₂ diffusion.

Hello, I run the Oase Biomaster2 Thermo 350 on my tank and would like to buy the CO2 reactor and connect it to it. Which version should I choose? Additionally, the bypass would be recommended, right?

The right reactor is the d16: https://www.aquasabi.de/AquaCare-CO2-Reaktor-50. Since the filter has a pump output of more than 400 l/h, a bypass should be installed.

I've been using the device for 4 weeks now and I'm thrilled. The CO2 is completely dissolved, so there are no bubbles in the aquarium. (read more)

Funktioniert super!

Ich habe das Gerät jetzt 4 Wochen im Einsatz und bin begeistert. Das CO2 wird komplett gelöst, somit keine Bläschen im Aquarium. Außerdem ist so keine Technik im Aquarium, und das CO2 wird perfekt verteilt. Einen Blasenzähler braucht man nicht, weil man auch so sehr gut sieht, wieviel CO2 zugegeben wird, da der Reaktor ja durchsichtig ist und CO2 Blasen durch das Medium gefangen werden.

Der blaue Anschluss für den CO2 Schlauch könnte etwas massiver ausgeführt sein, das wäre mein mini Kritikpunkt.

The many bubbles in the tank bothered me extremely, so after some research I wanted to get this reactor. (read more)

Kann man machen

Mich haben die vielen Bläschen im Becken extrem gestört, daher wollte ich mir nach etwas Recherche diesen Reaktor zulegen. Positiv ist dass er durchsichtig ist und gereinigt werden kann, weshalb ich mich für dieses Modell entschieden hatte. Auch der Einbau ist einfach. Ich filtere mein 500l Aquarium über den Ultramax, um dessen Leistung nicht zu sehr zu drosseln habe ich den Reaktor an einen Tetra ex 1000plus angestöpselt. Tadaaaa keine Blasen mehr im Blickfeld, leider aber auch nicht die gewünschten 20mg Co2. Der Reaktor läuft nun 4 Tage mit mal mehr mal weniger Durchfluss, ich pumpe mehr Co2 ein als vorher aber der Dauertest bleibt maximal gerade so im Umschlag von blau zu grün. Das Ergebnis ist leider eher frustrierend und ich bereue den Kauf und extra Aufwand etwas. Ich teste noch ein paar Tage weiter und hoffe auf das Beste.
