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. ## 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.tn/products/494510422-aquarium-co2-system-2l-with-pressure-gauge-automatic-pressure-relief](https://www.desertcart.tn/products/494510422-aquarium-co2-system-2l-with-pressure-gauge-automatic-pressure-relief) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
