Aqua Rebell CO₂ Check – Refill for long-term tests

Precise CO₂ control for your aquarium

The Aqua Rebell CO₂ long-term test solution in the variants "CO₂ Check – 20 mg per litre" and "30 mg per litre" is suitable for all standard CO₂ long-term tests and enables reliable long-term monitoring of the CO₂ content in the aquarium. An optimal CO₂ level is crucial for the healthy growth of aquatic plants and should be monitored continuously.

A particular advantage of this CO₂ long-term test solution is that the measurement is independent of the aquarium water. This means that interfering factors such as humic acids have no influence on the CO₂ determination, ensuring a more precise and unadulterated measurement.

Precise CO₂ measurement for a healthy aquarium

  • Reliable CO₂ control – Prevents deficiency or oversaturation
  • Two variants – 20 mg/l for moderate CO₂ levels, 30 mg/l for demanding plants
  • Easy to use – Can be used directly with any long-term test, no mixing required

Optimal CO₂ supply for vigorous plant growth

  • Promotes photosynthesis – Ensures lush greenery and healthy plants
  • Improves the balance in the aquarium – Supports stable water quality
  • Durable & efficient – One bottle is sufficient for numerous tests

With the Aqua Rebell CO₂ Check 250 ml, you can keep an eye on the CO₂ concentration at all times and create the perfect environment for your aquarium plants. Ensure ideal CO₂ control now and optimise the growth of your plants! 🌿💧

Easy Carbo
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.

ProFlora Cylinder 1200 U - single-use bottle
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.

Nano CO2 Flipper
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.
