Crafted from durable acrylic, its sleek, low-profile design blends seamlessly into any aquascape. Available in multiple sizes, it offers tailored solutions for various aquarium volumes, ensuring efficient CO2 dispersal and easy maintenance for long-lasting performance. ## Description 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. Dive deeper into the detailed specifications provided below for your aquarium setup. Product Specifications: Aquario Neo CO2 Normal Original Diffuser Size: Small Disk Size: 12mm Tube Height: 5.65 inches Tank Size: 13 gallons or less Size: Medium Disk Size: 17mm Tube Height: 5.65 inches Tank Size: Up to 32 gallons Size: Large Disk Size: 24mm Tube Height: 5.65 inches Tank Size: 32 gallons or larger Review: Great diffuser with only fine bubbles - Looks small at first but don't let that scare you. Once you finish installing you'll be amazed at how efficient this thing work. It's perfect for me outta the box. I have not seen a single large bubble so far. Just fine micro bubble. If you want finer bubbles it's recommended to soak in bleach and follow what it tells you. Works hard for a tiny diffuser and this is their large one. Connecting the CO2 tubing to the diffuser is easy and don't over force it because it can only go in about 1/4" and that is pretty tight already. Highly recommended on 75g +/- Review: Very fine bubbles, Great diffuser! - Fantastic diffuser. The bubbles are very fine and flow out very evenly. It also starts to bubble relatively quickly after the C02 is turned on and does not need a lot of 'built-up' pressure to start working. I've tried it a 1 bubble every 2 seconds to 2 per second, and it worked great in those ranges (I didn't try more or less but have no reason to believe it wouldn't work equally as well. It's a bit more expensive than the traditional glass diffusers with the embedded white disc but it also works much, much better. I like it enough that I'm going to try their similarly designed air stone. ## Features - [Super Fine Mist] Optimize the growth of your aquarium plants equipped with tiny nanoholes.

Very easy to hook up just the co2 line hooks up and you got it. The one I got is about the size of a quarter, I don't use a 1 way valve and it's never leaked. Great for the price and it looks okay but I hide it with plants ## Frequently Bought Together - Aquario Neo CO2 Aquarium Diffuser - CO2 Diffuser Aquarium Kit, CO2 Diffuser for Aquarium Plants, CO2 System for Aquarium - Normal Original Diffuser, Large - Aquarium CO2 Proof Tubing 16 Feet (Clear) - Glass CO2 Drop Checker – CO2 Monitor Kit for Aquarium Tank – Functional and Reliable – Transparent Drop Checker, 4dkh/pH Reagent Solution and Suction Cup --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/131248188-aquario-neo-co2-aquarium-diffuser-co2-diffuser-aquarium-kit-co2](https://www.desertcart.ni/products/131248188-aquario-neo-co2-aquarium-diffuser-co2-diffuser-aquarium-kit-co2) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-23*
