Fits Australian CO2 tanks including Kegland & Keg King
1) Equipped with Dual Gauge
- A big advantage over the single gauge type
- Very important for avoiding accidental CO2 dumping which can be harmful to fish/shrimp
- Displays pressure in your CO2 tank and pressure being sent through to your aquarium
- The meter showing pressure in your CO2 tank can help you know when the CO2 is finishing so that you can preplan in advance on when you need to refill or swap your CO2 tank (this helps you avoid the situation of CO2 supply suddenly running to 0 and you are not having sufficient time to get your CO2 tank refilled or swapped which can lead to algae issues in high tech tanks)
2) Excellent quality and very reliable while being much cheaper than high-end brands (high-end brand easily costs $200 and some do not have local Australian warranty)
3) Complete with Solenoid, Bubble Counter with a built-in check valve to avoid accidental water backflow which can cause equipment damage
4) Fits Australian CO2 gas tanks including Kegland and Keg King tanks
Aquarzon like these gas tank brands as they offer easy swap-and-go service in hundreds of outlets nationwide including at brewery stores and selected aquarium stores
5) With an Australian plug (so no worry of loose adapters, etc.)
6) 100% Original for reliability (Aquarzon purchases the stock directly from the manufacturer to ensure this)
Need CO2 tubing?
Just let us know in the Order Note during checkout and we will put in free high-pressure CO2 tube for you :)
Our high-pressure CO2 tube is made of PU and usually costs a few times more than standard silicone or PVC tube as it is much more durable and stronger as it can handle very high-pressure CO2 gas.
It can handle 150 PSI pressure rating (you would only need 50 PSI pressure to have CO2 pumped into your aquarium.
Many beginners do not know but using standard tube is one of the main causes of CO2 leakages or unstable CO2 which can lead to algae issues and CO2 tank being emptied quickly which is costly.
Protected by Aquarzon 3 Years Exclusive Brand New Replacement Warranty
with Australia Post Express covered
This is an exclusive warranty service whereby if your unit is faulty due to a core manufacture defect, we will replace it for you with a brand new unit and even send the replacement by Australia Post Express and cover all that.
This is way better than all other standard common warranties.
It is so, so much faster and you are getting a brand new unit instead of a repaired or refurbished unit.
For a standard warranty, you need to send the unit back to the retailer/manufacturer. After that, you need t spend additional time waiting for a faulty unit to be repaired. Once it is repaired, the repaired unit is sent back to you by standard post whereby you need to wait quite some time again. Or you might be given a refurbished unit with a risk of a fault repeating again. This can take a long time (easily 3-5 weeks or even 1-2 months if the retailer/manufacturer is overseas)
But for our exclusive warranty, it is designed specially to make it really easy for customers to get them replaced ASAP in an unfortunate case of core manufacture defects (once we receive your faulty unit and determine validity, we will Express Post and once posted, you can get your brand new replacement in usually just 3 working days).
Our process is very easy. After a quick photo/video assessment to help determine validity, you can send it back. We will check to confirm validity and once confirmed, we will then post a brand new unit by Australia Post Express to you.
Everything can be settled in just days. And yes, you are getting a brand new unit. Not refurbished and not repaired unit but 100% brand new.
It is important to understand that when you are spending on a CO2 regulator, warranty service is important.
Buying on eBay or general marketplaces will not get you a 3 years brand new replacement Australian-based warranty with Express service like this.
We will even post the brand new replacement by Australia Post Express so that it arrives to you ASAP.
It is quite often for the usual standard warranty, it only offers only a repair option or replacement for a refurbished unit. And even if it is not, it is usually posted by standard post. Some are even posted from overseas. All of these take so much additional time.
The repair option is troublesome and very time-consuming. It would take so much additional time with you waiting for the unit to be fixed after sending it back. Also, some brand return centres are overseas so one problem can take months to solve which means your aquarium will have a CO2 addition supply cut off suddenly for months. In high tech tanks, this can start the process of massive algae issues.
As for us, we are fully based in Australia so returns are quick. Our option of replacement for a brand new unit also means you do not need to wait for any faulty unit to be repaired. You save so much time and save your aquarium from the risk of algae issues. Getting a brand new unit also avoids the risk of an unfortunate issue repeating again (unlike a repaired or refurbished unit).
Aquarzon also extends the warranty period by additional 2 weeks from the purchase date to take into account shipping time and your installation time.
We totally understand that when there is a rare case of a manufacturing defect, it is already inconvenient. So we are here to help it minimise any inconvenience and get it replaced ASAP for you. Our warranty is very reasonable, it covers all core manufacture defects which cause the unit unable to perform its core function of regulating pressure and supplying CO2 to the aquarium tank. It does not cover wear and tear, slight aesthetic issues like small scratches, damages caused by users such as dropping it on a floor, damages by own water backflow intake, disassembly, natural disasters like floods which is totally beyond our control or similar, etc.
Why Choose This
Aquarzon understands just how hard it can be when it comes to choosing a CO2 regulator. You would want it to be very reliable but at the same, not one that cost too much.
Some people would say you pay what you get. To some extent, it is true. But it depends. You can certainly get some better-valued CO2 regulators. This means you can get very reliable ones without paying top dollar.
After long research, we settled on this and felt it is the right choice. We decided this based on durability, reliability, performance and price. We wanted something that is durable and reliable but still as affordable as possible.
We use multiple units of these ourselves to add CO2 to more than 20+ aquariums/setups.
If they are not reliable, we would not have used them ourselves.
Aquarzon has been using the ZRDR CO2 for a long time and they have proven to be very reliable. Best of all, it is very reliable while being much cheaper than high-end brands.
They have been performing very well with no major issues encountered.
Aquarzon feels that this CO2 regulator offers very good value for money as it offers excellent quality, performance and stability without being overly expensive (some good quality brand ones are easily $200 and some do not even have local Australian warranty).
On the other hand, cheap generic CO2 regulators can be unstable, often encountering malfunctions (solenoid not shutting or opening, etc.) and carry a much higher risk of issues such as a higher chance of CO2 leakage especially if they are not manufactured properly. Solenoid malfunctions can cause CO2 to run non-stop which can kill all fish and shrimp in a tank (lack of oxygen).
High-end brands, on the other hand, offer performance and stability but can come at an overly expensive price.
As such, this 100% original ZRDR Dual Stage CO2 Regulator appears to offer to best of both worlds by being great value for money as it provides great quality while being much cheaper than high-end brands.
This CO2 regulator is also dual gauge which has a big advantage over single gauge types.
Two-stage regulators have a big advantage over single-stage regulators as they avoid the issue of dumping CO2 gas into the aquariums when carbon dioxide in the cylinder tank is finishing. While this does not affect aquarium plants, it can harm fishes and shrimps including crystal shrimps and cherry shrimps.
With this CO2 regulator, it is easy to monitor pressure through the Internal Pressure Gauge and Delivery Pressure Gauge. You can also accurately adjust CO2 output.
The thread conforms to Australian standards (AS2473 Type 30 W21.8). If you plan to use Australian standard CO2 cylinder tanks such as Keg King and Keg Land CO2 2.6kg and 6kg cylinders, this CO2 regulator will fit in very well once you tighten it properly.
This comes with full retail box which includes:
Dual Gauge CO2 Pressure Regulator With Magnetic Solenoid Valve
Glass & Metal Bubble Counter (with built-in check valve)
Installation Tools (Spanner)
If you need free CO2 high-pressure (4mm inner diameter, 6mm outer diameter) airline hose, feel free to write that down in the Order Comments/Note part and if we have them available, we will give to you free.
All you would then need to set up your CO2 system for your aquarium is just to get the CO2 cylinder tank (Keg King or Keg Land usually sells them for just around $68 for a 2.6kg CO2 full cylinder) and the CO2 diffuser. You can get the stainless steel CO2 diffuser in our other listing.
