Introducing the Aquario Neo Aquarium CO2 Kit, a versatile addition for optimal aquarium CO2 distribution. The Normal Special series closely resembles the Normal Original Diffuser in size but differs by omitting the built-in aquarium bubble diffuser counter for a sleek appearance. For smaller aquariums, the Aquario Neo CO2 Normal Tiny features a compact design suitable for both rimless and rimmed tanks. Although lacking a built-in ceramic bubble diffuser counter, the Tiny series offers a clean and unobtrusive profile, enhancing the overall aesthetic of your aquascape. Crafted with precision and durability in mind, Aquario Neo CO2 diffusers are constructed from quality acrylic material, offering resilience against potential breakage and ensuring longevity. Equipped with tiny nanoholes that facilitate the creation of the finest CO2 aquarium bubbles for efficient dispersal and dissolution of CO2 for a complete CO2 system for aquarium setup. For optimal performance, soak the diffuser in water for 30 minutes before use to produce smaller bubbles. If bubbles enlarge over time, soaking the diffuser in bleach for 10 minutes, followed by thorough rinsing, ensures the restoration of functionality. Select from a diverse array of variations of a CO2 kit for aquarium plants, each offering distinct features tailored to your aquarium's needs.
