The bubble gauge is equipped with a syringe, which can be directly used to inject water (there is a one-way valve inside the generator, only into the water without leakage). And you can also add water during use, no need to close the air outlet, no need to remove the air tube, convenient for your use - High Security: Automatic pressure relief valve, when the pressure of the inside co2 steel bottle exceeds 30KG will automatically release pressure. 12V Waterproof solenoid valve， Keep away from the danger of water leakage from the solenoid valve, protect your safety - Refine The Bubbles: Our CO2 aquarium kit is equipped with an atomizer, which can purify bubbles, make them easily soluble in water and absorbed by plants, and make your aquarium full of vitality. We also gave you an extra atomizer as a replacement to extend the service life of the product. When using this product for the first time, there will be large bubbles in the refiner, which will gradually disappear within 3 days - Low Cost: You only need citric acid, baking soda, and water which are available in supermarkets. When the gas in the bottle runs out, you only need to purchase the material again - Professional Factory and Peace of Mind After-Sales: We are a manufacturer specializing in CO2 generator systems.

That’s what I bought it for. I have a 4x4 tent. With that being said, I would just buy a co2 tank and regulator if I had to do it over. The co2 will only last around 2 hours at 1500ppm. All the mixing required gets old and it’s a sticky mess. But it does work, sorta. Bottom line, save up 300 more and get a real co2 system. **Q: How tall is whole assembly without the tank base? I have a stand with 17.5 inches of clearance, want to make sure it fits** A: Not sure but the stand does not add height. I dont think youll make it with 17 inches. **Q: Will this work on a 150 gallon planted aquarium?** A: Yes **Q: which CO 2 generator recommend for a 40 gallon aquarium** A: I'd use the ZRDR 4L i have it on my 55 been almost a month and still has a good bit of time before empty. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by 3***O on June 21, 2024* ### ⭐⭐⭐⭐⭐ Review *by M***O on August 21, 2023* ### ⭐ Review *by F***P on May 18, 2021* ## Frequently Bought Together - ZRDR Aquarium Co2 System 2L with Pressure Gauge Automatic Pressure Relief Valve Bubble Counter for Aquarium Plants，Stable Output - Milliard Citric Acid Powder Food Grade, 2 lb Bag, Bulk, 100% Pure Citric Acid Food Grade, Non-GMO Project Verified, Cleaning, Bath Bombs, Cleaner, Descaler, Dishwasher, Candy, Acido Citrico en Polvo - Milliard 10lbs Baking Soda / Sodium Bicarbonate USP - 10 Pound Bulk Resealable Bag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/494510422-aquarium-co2-system-2l-with-pressure-gauge-automatic-pressure-relief](https://www.desertcart.us/products/494510422-aquarium-co2-system-2l-with-pressure-gauge-automatic-pressure-relief) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
