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.

Plant foodHealthy plants are important for every aquarium. Plants supply the aquarium with vital oxygen for the aquarium inhabitants, prevent algae and remove problematic substances.
Healthy fish = healthy plantsHealthy plants prevent algae growth, supply oxygen, remove pollutants, provide hiding places and reduce pathogens. The following needs should be met in order for plants to thrive: Light as an energy source for photosynthesis CO2, nutrients and trace elements as growth promoters JBL plant fertilisers supply the plants with all the main nutrients and essential trace elements via the water. In this way the plants receive all the nutrients they need for absorption via the leaves and roots.
Nano Co2 Flipper - A new, highly effective yet extremely compact CO2 diffusor designed especially for mini aquaria
Effective dissolving of CO2
Integrated bubble-counting function
Incl. waste gas vent
How it works:
The CO2 bubbles issue from the opening at the bottom of the Flipper and rise along the channels. Part of the CO2 dissolves in the aquarium water in the process. The rest accumulates in the collector, from where it is released into the water. The safe design of the collector ensures that the small quantities of CO2 which are customary for nano aquaria are effectively dissolved, while undesired large quantities of CO2 are discharged automatically via the waste gas vent. The scope of delivery thus includes 2 collectors – the smaller one for 10-25 l aquaria, and the larger one for 25-40 l aquaria.
The crucial advantage over the CO2 diffusors with ceramic membrane which are commonly used for nano aquaria is that the Nano Flipper does not produce any counterpressure. This means that it responds directly to changes on the pressure reducer. The required (small) quantity of CO2 required can thus be set reliably within a few minutes.
The CO2 Nano Flipper consists of highly transparent, break-proof plastic "Made in Germany" and can be combined with all standard CO2 supply systems. We recommend the Dennerle CO2 Nano Set.All CO2 hoses with an external diameter of 6 mm can be used.
Rule of thumb for basic setting:
Start with approx. 1 bubble per minute, per 10 l aquarium water, this means for example, approx. 3 bubbles per minute for a 30 l aquarium.The CO2 concentration is measured in the simplest possible way with the Crystal Line CO2 long-term test Mini. If the test is GREEN, the water contains exactly the right amount of CO2.

Package contents: extension for CO2 high-performance diffuser, ProFlora Taifun Extend, incl. 1 retaining clip, 1 suction holder
Ideal nutrition for plantsThe right CO2 concentration in the water is of great importance for the aquarium plants. Carbon dioxide is the main nutrient for plants and promotes their growth. Plants use the CO2 for the photosynthesis and thus supply the water with essential oxygen. They prevent algae growth, remove pollutants, provide hiding places and reduce pathogens.Even enrichmentThe JBL diffuser supplies the aquarium water with the main plant nutrient CO2 in even-sized bubbles.Easy installationPull off the lower end cap of the JBL Taifun, remove the hose and put the extension modules in-between. Push the hose through, attach it to lower end cap and re-attach the end cap on extension module. Now your diffuser has been extended by the extension modules.EffectiveThe correct amount of CO2 varies from aquarium to aquarium and depends on the volume, the water movement and the planting of the aquarium. You can check the CO2 content by means of a CO2 test.
