The ARKA Carbon filter C2 pre-filter for the myAQUA 400 is a replacement part designed to enhance the purity of the water produced by the reverse osmosis system. Used in conjunction with the C1 filter, it provides additional carbon filtration to further reduce traces of chlorine, pesticides, herbicides, and pharmaceutical residues . Thanks to its premium coconut-based activated carbon , it offers excellent adsorption capacity and contributes to cleaner, more stable, and more reassuring water for both freshwater and reef aquariums. Easy to integrate into the ARKA myAQUA 400 system , this pre-filter also helps maintain good overall performance over time.
The ARKA C2 carbon pre-filter was designed to act as a second carbon filtration stage in the myAQUA 400 system. While a primary carbon filter already does a significant portion of the work, the C2 refines the result and captures any remaining unwanted substances in the water. This additional filtration is particularly beneficial for aquarists seeking the cleanest possible reverse osmosis water, with an extra level of safety before use in the tank.
In practical terms, this pre-filter helps eliminate residual traces of chlorine , as well as various chemical contaminants such as pesticides, herbicides , and certain pharmaceutical residues . In a well-maintained system, this type of component truly makes a difference, providing a valuable finishing touch to filtration, especially when the incoming water is heavily contaminated or its quality fluctuates over time.
One of the major advantages of the ARKA C2 Carbon Filter is its use of high-quality coconut-based activated carbon . This material is valued for its high adsorption capacity, meaning its ability to effectively retain numerous undesirable substances. This is a real benefit for reverse osmosis water production, as it allows you to achieve cleaner water without complicating the system.
For aquarists, this level of filtration translates into water that is better prepared for the needs of fish , corals , invertebrates , and even aquatic plants . Cleaner water from the start also provides a better foundation for the overall stability of the tank. In both reef and freshwater aquariums, this level of water quality is often what prevents many problems in the long run.
The C2 carbon pre-filter doesn't work alone. It was designed to work in tandem with the C1 filter in the ARKA myAQUA 400 system. This dual carbon filtration system enhances water purification and provides more consistent results. For myAQUA 400 users, this is a coherent, easy-to-maintain setup, perfectly suited for proper reverse osmosis system maintenance.
This direct compatibility is a real advantage, as it avoids makeshift installations or the use of poorly adapted generic parts. Here, the replacement part has been designed specifically for the system in question, with performance perfectly suited to its intended use. This is exactly what you want when you want to keep your reverse osmosis system reliable, practical, and efficient on a daily basis.
The ARKA C2 pre-filter is suitable for preparing water for both freshwater and marine aquariums. It's designed for enthusiasts who want consistent water quality, whether for a community tank, a planted aquarium, or a more demanding reef tank. Its purpose is clear: to complete the filtration process in the carbon section and further improve water quality before use.
To maintain this level of performance, regular maintenance is essential. It is advisable to monitor the quality of the reverse osmosis water , its conductivity , and the overall flow rate of the system. In practice, replacing the pre-filter is recommended every 6 to 12 months , depending on usage and the quality of the incoming water. As soon as a decrease in performance is noticed, it is best not to wait to change the cartridge.
The ARKA Carbon Filter C2 is a replacement part that brings real benefits to the entire system. It doesn't just add another layer of filtration; it refines the existing process to provide cleaner, more stable water, better suited to the needs of modern aquariums. Its coconut-based activated carbon , compatibility with the myAQUA 400 , and supplementary filtration function make it a logical choice for properly maintaining your reverse osmosis system.
For those who want to maintain a high level of filtration and prevent unwanted traces from passing into their reverse osmosis water, this filter is ideal. It's a simple, effective, and reliable solution for continuing to produce quality water, whether from fresh or salt water.

The osmosis units of the easy line 190 and easy line 300 series are compact and efficient. The fine filter removes all particles larger than 5 μm. In our facilities we use TFC (Polyamide/Polysulfon) membranes. The installations operate with an output of approx. 3 - 4:1 (rejection:permeate) and have a salt removal capacity of approx. 95%.
