ME Carbo Ultra Flex – CO₂ system without a cylinder for tanks up to 400 litresME Carbo Ultra Flex CO₂ system (without cylinder) for aquariums up to 400 litres. Includes pressure regulator, solenoid valve, diffuser and continuous CO₂ test. Suitable for disposable and reusable cylinders.The ME Carbo Ultra Flex is a high-quality CO₂ fertilisation system designed to supply aquatic plants with carbon dioxide in a targeted manner. This well-designed system was developed for demanding plant aquariums and aquascapes and is suitable for freshwater aquariums with a volume of up to 400 litres.Carbon dioxide (CO₂) is an important component of photosynthesis, alongside light and nutrients. A CO₂ supply tailored to your plants’ needs supports healthy plant growth, strong leaves and vibrant plant colours. Controlled CO₂ fertilisation can make a significant difference, particularly in heavily planted aquariums with powerful lighting.At the heart of the system is the ME Regulator Ultra pressure reducer with an integrated solenoid valve. It allows for precise adjustment of the CO₂ supply and offers the option of automatically interrupting the gas supply during the night. The solenoid valve can, for example, be connected to a timer for this purpose.The integrated bubble counter with non-return valve makes it easier to monitor the CO₂ dosage. The desired number of bubbles can be set using the fine-adjustment needle valve, whilst two pressure gauges display the cylinder pressure and the set operating pressure.The CO₂ Diffuser Pro L, included as standard, ensures the fine distribution of carbon dioxide in the aquarium. It releases the gas into the water in the form of tiny bubbles, thereby promoting the most efficient possible dissolution of CO₂.To monitor the CO₂ concentration, the set includes a CO₂ Check Glass continuous test kit with 15 ml of test liquid. The colour change of the indicator liquid allows for easy monitoring and helps you adjust the CO₂ supply to the actual needs of your aquatic plants.A particular advantage of the ME Carbo Ultra Flex is its flexibility. Thanks to the adapter supplied, the system can be used with both suitable disposable CO₂ cylinders and reusable cylinders. This allows the system to be adapted to different aquarium sizes and existing CO₂ set-ups.The ME Carbo Ultra Flex offers a convenient solution for aquarists who value a precise, reliable and individually adjustable CO₂ supply.Important: The CO₂ cylinder is not included and must be purchased separately.Your benefits at a glance1 CO₂ fertiliser system ( cylinder not included)Suitable for planted freshwater aquariums up to 400 litresRegulator Ultra pressure reducer with dual pressure gaugeIntegrated solenoid valve for automatic night-time shut-offBubble counter with non-return valve and precise fine-needle valveDiffuser Pro L for fine CO₂ distribution in the aquariumCO₂ endurance test included, with test fluid for monitoringSuitable for use with compatible disposable and reusable CO₂ cylindersContents of the packME Regulator Ultra pressure regulator with integrated solenoid valveCO₂ Diffuser Pro LFlexTube CO₂ hose, 2 m longAdapter for use with disposable cylindersCO₂ Check Glass Long-Term Test15 ml CO₂ test solutionInstructions for usePlace a suitable disposable or reusable CO₂ cylinder upright in a safe and well-ventilated location near the aquarium.

Start with a low bubble count and gradually increase the supply in line with your plants’ requirements.The included CO₂ continuous test kit indicates the approximate CO₂ concentration in the water via the colour change of the test liquid. Check the value regularly and adjust the dosage as required.The integrated solenoid valve can be connected to a suitable timer to automatically interrupt the CO₂ supply during the night.Important safety instructionsAlways position CO₂ cylinders upright and secure them to prevent them from falling overOnly use suitable and approved CO₂ cylindersCheck the connections for leaks before commissioningDo not use oil- or grease-based lubricants on pressure connectionsAdjust the CO₂ supply slowly and in a controlled mannerMonitor the CO₂ concentration regularlyProtect your fish immediately if there are signs of CO₂ overdoseShut off the gas supply and disconnect the power supply before carrying out any maintenance workZoo Roco TipA well-balanced CO₂ supply is particularly important in heavily planted aquariums and demanding aquascapes. To ensure your aquatic plants can grow optimally, the lighting, CO₂ and nutrient supply should be as well-balanced as possible.For many planted community aquariums, the target CO₂ level is around 20–30 mg/l, provided that the fish and shrimp population can tolerate this concentration. Check the levels regularly using the continuous test kit supplied.Our tip: Connect the built-in solenoid valve to a timer and synchronise the CO₂ supply with the lighting schedule. This allows you to conveniently control the supply to your plants and avoid unnecessary CO₂ addition during the night.Thanks to its flexible connection options, the ME Carbo Ultra Flex is particularly suitable for aquarists who already own a suitable CO₂ cylinder or wish to switch between disposable and refillable cylinders at a later date.

Easy Life Carbo Liquid carbon fertiliser CO₂: simple and effective. Effective carbon fertiliser promotes good plant growth   Plant growth prevents the growth of algae also helps against cyanobacteria Dosage: A lightly planted aquarium: 1 ml per 50 litres daily A densely planted aquarium : 1 ml per 25 litres daily ProFito plant fertiliser and EasyCarbo carbon fertiliser is the right combination.EasyCarbo is a very powerful and efficient source of carbon for aquarium plants. Carbon is essential for plants. The fertiliser can be used for aquariums with or without additional carbon dioxide fertilisation. A strong growth spurt is noticeable after just a few weeks. EasyCarbo increases the competitive power of plants against algae and at the same time contributes to their reduction. The product is ideal for combining with the plant nutrient ProFito. Algae no longer stand a chance Plants assimilate and grow much better because of the carbon from EasyCarbo. Especially marsh plants such as Cryptocoryne sp. and Echinodorus sp. react positively, as EasyCarbo is very easily absorbed. They grow much more vigorously and look more beautiful and fuller. The more vigorous growth of underwater and marsh plants causes a reduction in algae. Brush algae, beard algae and the like really don't stand a chance any more. The use of ProFito complete fertiliser and EasyCarbo carbon fertiliser is the right combination! Plants need more than just carbon. Trace elements are also essential. Trace elements can never be measured exactly and as we do not know which trace elements are present in the water, ProFito is the ideal solution to enrich water comprehensively with trace elements.

Disposable CO2 bottleThis disposable CO₂bottle supplies your aquarium plants with their main nutrient, carbon dioxide (CO₂). Turn the pressure regulating fitting with internal thread onto the external thread (M10x1) of the supply bottles, and you are ready to go. The pressure bottle should always stand vertically as long as it is in use.Scope of delivery: disposable cylinder, ready-filled with 1.2 kg CO₂, dimensions: approx. 45 × 10 cm, thread M10x1Easy installationIncluding mounted rubber standTÜV-testedTotal height with mounted pressure reducer: 37 cmCO₂ disposable bottle or CO₂ reusable bottle?There are two different types of bottle: Disposable bottles, which are disposed of as well as recycled after emptying, and reusable bottles, which could be refilled again and again. Refilling can be done by pet shops and gas companies. If you live in a region where refilling is problematic, for example, the disposable bottle would be an alternative. If the refilling situation improves, you can convert the disposable pressure reducer into a reusable pressure reducer in 2 minutes by screwing on the adapter (JBL PROFLORA CO2 ADAPT u-m). Aquarists who live on islands, for example, are sometimes not allowed to transport filled reusable bottles on ferries or planes. Disposable bottles are then sometimes allowed! (Please always clarify exactly)The size of the bottle often depends on the cupboard below where the CO₂-supply bottle is placed: a 500 g disposable bottle is only 31 cm high (plus pressure reducer = 37 cm), a 500 g reusable bottle with stand is already 43 cm and a 2000 g bottle 45.5 cm high. In principle, of course, a larger bottle is advantageous because it simply needs to be replaced or refilled less often.
