I weld and have a few regulators for welding gas. Nonr are as well built as this one. New to the planted aquarium hobby. This the first full sized purposed built CO² regulator for aquariums.A few key points I like:1. Packaging- a very over looked aspect in many items. No way was this thing getting damaged.2. Quality- as Fair as a visual inspection and feel test. This is a solid regulator.3. Knurled knob- love the knurled knob! Attention to detail4. Extra o-rings- great to have spares5. Spanner- this regulator comes with a wrench I think is made of some sort of steel covered in plastic. It pretty thick so you don't hurt your hands thighten done the regulator to the bottle.Just installed it with a kegco 5lb CO² bottle. Everything looks good so far. Will adjust score and review later if anything happens. ### ⭐⭐⭐⭐ works and is reliable. *by C***E on Reviewed in the United States on December 9, 2018* I have this regulator hooked up to a paintball tank with a CGA320 adapter and my Samsung Smarthings plug with Alexa. This thing is reliable and turns on\off with out any issue. I had an Aquatek that cost more $$$ and was just not reliable, as it would not turn off when it was supposed to. I changed the orientation of one of the gauges so I could read it upright when mounted on the paintball tank. The only thing I would improve is bigger gauges. One big plus is red indicator light on the solenoid when its one is a nice plus as it gives positive confirmation that the valve is open. ### ⭐ JUNK!!!! DO NOT BUY!!! *by R***I on Reviewed in the United States on February 11, 2019* Had the regulator hooked up for less than 2 weeks. Everything worked fine and it was small and compact. Yesterday the solenoid failed to open when power was supplied to it. Unplugged the solenoid from the timer and plugged it back in and everything worked fine the rest of the evening. Skip ahead to 5 pm when I get home tonight. Walk by my tank and notice the co2 drop checker is dark blue again and there is a sound coming from under my tank. Look and my co2 tank is almost completely empty! The regulator randomly developed a leak today, between the regulator and the solenoid, while I was at work. I guess this is what I get for listening to the positive reviews and not the negative ones. This regulator is junk, DO NOT BUY! --- ## 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.hr/products/90209751-aquarium-co2-regulator-mini-dual-gauge-display-with-bubble-counter](https://www.desertcart.hr/products/90209751-aquarium-co2-regulator-mini-dual-gauge-display-with-bubble-counter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
