It features an integrated pressure gauge, automatic pressure relief valve, and an upgraded bubble counter with syringe refill capability for hassle-free maintenance. Designed for aquarium plant enthusiasts, it uses safe, low-cost ingredients (citric acid, baking soda, water) to produce stable CO2 output, enhanced by an atomizer that refines bubbles for optimal plant absorption. This system combines safety, efficiency, and durability to keep your aquatic plants thriving with minimal ongoing costs. ## Description Stainless steel pressure reducing valve and pressure gauge,no need to buy separately.Our CO2 generator system is different from traditional:traditional carbon dioxide generators need to inject gas into the bottle. Our CO2 generator system can generate CO2 by itself. You only need to add the appropriate amount of citric acid, baking soda,and water to generate CO2. When the gas in the bottle is used up, add the material to the steel bottle again.Main materialStainless steelsize2L:Height: 53cm; diameter:10cm;thickness: 0.12cm.Raw material ratioCitric acid 200g+baking soda 200+water 300gIt’s more professional and efficient because all the accessories you need are included. 1. 2L steel bottle body2.

Review: If you don’t have a local canister refill supplier then this is an excellent way to get a consistent bubble count. It looks good, is easier to use than a DIY system, and the materials (citric acid powder and bicarbonate soda powder) can be ordered in bulk online and are quite cheap. Well made and reliable. Review: ZRDR Aquarium Co2 System 2L with Pressure Gauge Automatic Pressure Relief Valve Bubble Counter Purchased 20 May 2024 from ZRDR for $77.99 WARNING: SERIOUS INJURY OR DEATH CAN OCCUR, DON'T DO THIS This is a nonstandard use of the ZRDR CO2 system. This is more of a product suggestion than a review. For the price, this kit is outstanding for the original intended purpose (aquarium) IMHO. This modification is not for the risk adverse, feint of heart, uneducated, nor unskilled. I am merely illuminating what I have done in the hopes that ZRDR will make a professional system for the masses (product suggestion). In the beginning...there was the SodaStream Art by Pepsico. Then I converted this thing to replace the Art and gave the Art away. I just didn't want to fool around with their reasonable $15 60L CO2 canister exchange program, preferring to make my own CO2 from reactants (baking soda and citric acid). I mean come on, making CO2 is cheap and easy. Upfront investment cost is about the same. Recurring costs can be less, providing local access to low cost reactants. At 200g per charge, 5lbs is 2268 grams yielding 11 charges. For convenience, the reactants are sold right here on desertcart: https://www.desertcart.com/gp/product/B000OZFECU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 https://www.desertcart.com/gp/product/B0774M73SF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 This project does require know how and mechanikin' skillz. There are two basic options, modify this canisters OEM top cap permanently destroying the built in regulator and removing everything past and including the bubbler (port in cap for bubbler is 1/8" BSPP), or drill and tap an M30x1.5mm plug using a ~34x28mm O-ring: https://www.desertcart.com/gp/product/B0BCFB7PBV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Then it's basic plumbing parts until the bottle. I clear Epoxy all plumbing joints. I used two ball valves and a pressure gauge so I could check the canister and bottle pressure, all 1/4" NPT. Then a pressure washer quick disconnect: https://www.desertcart.com/gp/product/B07RHK7HK2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 https://www.desertcart.com/gp/product/B08F2X5L24/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Then drilled a replacement SodaStream bottle cap with 3/8" brad point drill bit then 13/32" and thread with 1/4" NPT tap, appropriate washer threaded 1/4" NPT, epoxy and a 1/4" compression fitting: https://www.desertcart.com/gp/product/B0CZ32LWCC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 And a check valve between pressure washer QD and 1/4 compression fitting: https://www.desertcart.com/gp/product/B0BN6HL5B3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Then there are two options for the 1/4" stainless tube. From the underside of the bottle cap to the end of tube assembly should be 3+1/2 to 3+5/8 inches long. Easiest was to use a piece of this tube and crimp end in vise for small holes ~1mm: https://www.desertcart.com/gp/product/B0006NAUQK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Fill Sodastream bottle with water to line, chill in fridgedator, screw on and three *quick bursts. NOTE: releasing Sodastream bottle pressure between each burst (I just unscrew bottle from cap). At the end of each burst the bottle pressure should read ~55psi. I should have added a 55psi regulator. This is INHERENTLY DANGEROUS as the Sodastream bottle can be pressurized to way more than 55psi. The second method for the tube assembly that I preferred was to use heavy wall (0.065" wall) stainless 1/4" tube, drill and tap for 3/16-24, then use a vented socket head stainless screw (0.046" hole = 1.1684mm). Both purchased elsewhere. Sodastream bottles and caps here: https://www.desertcart.com/gp/product/B01AHGDQ3Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 https://www.desertcart.com/gp/product/B004OYMOK2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Amount of CO2 in soda is amazing. I get 6 to 10 1L carbonized Sodastream bottles out of a single baking soda and citric acid charge. At 11 charges that is at least 60 1L bottles carbonized, up to 110. When ZRDR canister pressure drops to below 100psi, I pressurize the Sodastream bottle assembly, then QD and shake vigorously for 10-45 seconds, let sit in fridge for a bit to get more 1L carbonized bottles out of a single charge. This is the reason for the QD and check valve on bottle cap assembly. I like this method for many reasons, the added bonus is it doesn't leak so CO2 waste is minimized. But it lacks a safety release and regulator making it INHERENTLY DANGEROUS. Some notes: I did some research and lots of R&D on this project. What I show here is what I ended up with that IMHO works best. DO NOT use more than 200g of baking soda, 200g of citric acid, and 300g of water in this canister. Pressure will build to 270psi (room temperature) after a couple days unless you use some of the CO2. The canister safety release built into the OEM top cap is advertised for 30Kg/cm2 which is 426psi. My method shown here eliminates that safety release which is DANGEROUS and NOT recommended. I should have added a 300psi 1/4" NPT safety release sold right here on desertcart. Ordinary soda bottles have a burst pressure of 12bar which is 174psi, though there is yielding way before burst, I do not use ordinary bottles. Sodastream bottles are heavy wall and burst has been tested (one unit) at 25bar or 362psi, though there is yielding way before ultimate. Pepsico says this: "To successfully carbonate water with a CO2 tank, the gas regulator valve should be set at 55 PSI, to enable the serving pressure to remain at around 12 PSI." I should add a 55psi regulator, this method is dangerous as the Sodastream bottle could be pressurized way above 55psi. Pepsico advertises 4 years per Sodastream 1L bottle, not cycle dependent. The modification I made to the Sodastream bottle cap invalidates all of this. It would be best if a cap was specially made for this application (product suggestion). edit 23 July 2024 I ended up replacing the vented screw with a 0.8mm misting nozzle. Taking the misting nozzle apart and removing the spring and rubber check valve. This works much better. FYI 0.6mm is too small. https://www.desertcart.com/gp/product/B093L385FF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Also, I purchased a used 5.5L tank elsewhere and added an oxygen regulator, but that bottle needed a smaller o-ring stretched on the M30x1.5mm top cap, 1"ID by 1/8" thick. https://www.desertcart.com/gp/product/B073P1C18S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Notes: Helps to put glycerin on the o-rings. Helps to put a small 5" balloon in the tank and fill with water (ye old brass hose nozzle) then drop in tank and screw on top cap. Then shake. Balloon comes later for reuse. https://www.desertcart.com/gp/product/B07SR1P15T/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 ## Features - 【New upgrade bubble counter】As the water of the co2 generator system bubble counter evaporates quickly, In view of this, we have carried out a new upgrade to the bubbler. 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 & Peace of Mind After-Sales】 We are a manufacturer specializing in CO2 generator systems. Our co2 generator system is made of 304 stainless steel, far better than a simple plastic bottle generator, more durable, stable, safe, and high-pressure resistant.

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 J***R on 5 July 2024* If you don’t have a local canister refill supplier then this is an excellent way to get a consistent bubble count.
