Oxyturbo CO₂ Set Basic

The CO₂ Set Basic provides a solid foundation for CO₂ fertilisation in aquariums, including a reliable Oxyturbo pressure regulator, a crystal-clear CO₂ high-pressure hose, an Orb Checker Nano, CO₂ indicator solution CO₂ Check, a bubble counter, an energy-efficient solenoid valve, and a Neo CO₂ Diffuser. It is designed specifically for an affordable entry-level solution, offering everything needed for a stable and simple CO₂ supply. The focus is on ease of use, robust construction, and an attractive price-performance ratio.

The Oxyturbo pressure regulator reduces cylinder pressure from approximately 54 bar to a working pressure of about 1 to 3 bar. With the combination of working pressure and cylinder pressure gauges, the CO₂ supply can be accurately regulated, and it is easy to see when the cylinder needs to be refilled. The integrated fine needle valve allows for precise adjustment of the CO₂ supply. The separately available Hiwi Fixed spanner SW30 is ideal for securely attaching the regulator to refillable bottles.

The CO₂ high-pressure hose made of polyurethane is food-safe, absolutely crystal clear and without labeling. While PUR hoses are durable, they are not ideal for connecting to glassware. To ensure secure connections, the hose should be softened in very hot water before attaching it to fittings. Similarly, reheating the hose with hot water or a lighter before removing it from glassware reduces the risk of glass breakage.

The Aquasabi Bubble Counter is a valuable tool for monitoring CO₂ levels in aquariums. By counting bubbles over a set period, it allows for a rough estimation of CO₂ being supplied. The Bubble Counter has an integrated non-return valve whose main purpose is to prevent the backflow of aquarium water through the bubble counter into the technical system, such as the pressure reducer, especially when the supply pressure drops.
Using the bubble counter is simple and straightforward. The bubble counter is inserted into the system for optimized control of the amount of CO₂ supplied. The screw thread on the underside of the bubble counter is precisely manufactured to ensure a reliable connection with other components.

The CO₂ Drop Checker (Orb Checker Nano) allows for optimal monitoring of CO₂ levels in aquarium water. The Aqua Rebell CO₂ indicator solution included in the set changes colour based on the CO₂ concentration. Green indicates an ideal CO₂ level of 20 mg/l, blue signifies low CO₂, and yellow warns of excessive CO₂ concentrations.

The Bavaria Fluid Systems Solenoid Valve BMV61212 is a premium-quality 2/2-way coaxial solenoid valve manufactured in Germany, specifically designed as a night shut-off for CO₂ systems in aquariums. By halting CO₂ supply during the night when plants are not consuming it, the valve prevents CO₂ buildup and safeguards aquarium inhabitants. The normally closed valve has a low power consumption of just 1,6 W and operates reliably with a supply voltage of 230 V AC. Its robust construction, featuring stainless steel and nickel-plated brass, ensures durability, while its IP65 protection rating guards against dust and water. The valve’s connectors are compatible with standard 4/6 mm hoses.

The AQUARIO NEO CO₂ Diffuser Original is a compact acrylic CO₂ diffuser that efficiently atomises CO₂ through a specialised ceramic membrane, ensuring it dissolves effectively in water. It might be helpful to soak the diffuser in water for about 10 minutes before initial use to displace any trapped air. This could be particularly beneficial during the first 24 hours after installation to minimize the formation of larger bubbles at the bottom edge of the ceramic membrane. Alternatively, one could simply wait after connecting it to the CO₂ system, as the CO₂ will eventually displace the remaining air on its own.
