Solenoid valve seams pretty hot however. *by on Reviewed in the United States 6 March 2023* So far so good but I am a little concerned with the solenoid valve running pretty hot.It took less than 10 minutes to assemble and another 10 minutes to load with (in order) 200 ml citric acid, 250 ml of baking soda and then 300 ml of water. All while being held at a 45° angle. This order and angle buys you a few seconds to get the top screwed on before the gas really starts being produced. Once closed, I lightly swirled the tank to mix the ingredients and then I sat the tank in a pan of hot tap water for a couple of hours. When I came back it was in the middle of the green and I could still faintly hear more reaction happening. When I got up in the morning the pressure had risen to the middle of the white where it stabilized. A little high but well under the red. From what I can find, the perfect mix is 1:1.312 (CA:BS). My 40 gallon aquarium has a KH level of 5 and a normal PH of 7.58. It is taking 3 BPS to get my pH below 7 and my drop checker to a nice green. ## Frequently Bought Together - MagTool 4L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve (4L with Solenoid) - Milliard Citric Acid 5 Pound - 100% Pure Food Grade Non-GMO Project Verified (5 Pound) - Milliard 5lbs Baking Soda / Sodium Bicarbonate USP - 5 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.is/products/378082922-4l-aquarium-co2-generator-system-carbon-dioxide-reactor-kit-regulator](https://www.desertcart.is/products/378082922-4l-aquarium-co2-generator-system-carbon-dioxide-reactor-kit-regulator) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-07-19*
