Review on 🌱 2L ZRDR Co2 Generator System for Aquarium Plants - Pressure Gauge, Automatic Pressure Relief Valve, Bubble Counter, Stable Output - Steel Bottle Base Included by Cheryl Wilson

UPDATE April 24th 2021 I've been using this setup for a few months now and it's amazing. I change the baking soda and citric acid about every 2 weeks. The output was consistent and the issues I initially had with the meter not showing accurate readings are no longer an issue. My plants are doing very well. I highly recommend this setting and have changed my rating from 4 stars to 5. Original: After setting it up, I found this CO2 setting amazing. Here are some tips from my experience, step by step: 1. My cotton filter was already attached to the machine, which looks a little different than the instructions (part 3) stated. My kit also included a replacement cotton filter (part 4).2. Screwing the filter (part 3) onto the valve (part 2) was easy in my experience. Just tighten as much as you can.3. Use the funnel and fill the container (part 1) with the ingredients. NOTE: 200g is 7/8 cup. I made about 3/4 cup each of citric acid and baking soda, then 1 cup water. Next time I'll make 1 full cup of acid and soda and 2 cups of water. I didn't have enough supplies. Screw the pressure valve into the housing (Part 2 to Part 1)4 as tightly as possible. My valve didn't register any pressure to start. I have waited a long time. Finally giving in, I unscrewed the top screw over the gas release button on the valve and heard air escaping. I knew then that it produced well. I never reused this top screw after removing it.5. Connect the solenoid valve (item 6) and use the wrench (item 13) to tighten it securely.6. I unscrewed the entire top (the smaller end with the screw) of the bubble counter (item 5) and filled it 3/4 full with water. Reattach the top of the bubble counter securely and screw the other side (bottom) firmly onto the top of the solenoid.7. Remove the screw from the top of the bubble counter and slide the end of the rubber tubing (item 17 - "Trachea" in the instructions is the tubing) that contains the screw. Then slide the end of the rubber tubing over the top cone of the bubble counter where the screw was and screw the screw back in to hold the tubing in place. A NOTICE. The tube is rigid and quite difficult to machine. I am thinking of replacing them with better and more flexible hoses.8. Cut the rubber tubing twice - once about 4" from the bubble counter (save that 4" cut for later). The second cut is about 18 inches long.9. Firmly attach the check valve (item 12) to the other end of the hose that connects to the solenoid (the end with the filter inside the check valve goes to this end of the hose). The free 18” section of the cut tubing attaches to the other side of the check valve (open end of valve with no filter). 10. Attach the other end of the 18” section of pipe to the U-tube (item 14). This piece goes over the rim of your tank when you install it.11. Use the remaining spare 6" piece of tubing and attach it to the other end of the U-tube. Attached to the other end of these 6 sections is your atomizer (part 15). The CO2 kit is now ready for installation. Place the base on the bottle (item 16) and place it where you plan to store the device. Attach the U-tube to the rim of your tank and use the suction cups (item 11) to insert the 6 inch section of tubing between the U-tube now over the rim of your tank and the atomizer in place in your tank fasten the solenoid link valve (key 8) into the solenoid, then the power cord (key 7) to it. Once everything is in place, plug the power cord into an outlet to turn on the solenoid. the gas release button on the pressure reducing valve (literally a hair's breadth at a time) until you reach the target of one bubble per 10 gallons every 5 seconds. It took me a while to adjust to this process, but once installed it stayed in place. On the day of the tuning, my pressure valve showed no pressure. The bottom of the stainless steel case got very cold and my bubbles produced a certain number of sets so I knew everything was working fine. Found that the valve was defective. However, the next day it hit 10-15 or so in the green. I plugged into the wall clock and set it for 8am to 6pm. It takes about 30 minutes in the morning for the pressure to fully recover. So far it has been very stable throughout the day. Also, I agree with other reviewers that the solenoid gets pretty hot. Mine doesn't get hot like others have described, but it does feel quite warm. I'll keep an eye on it, as well as the bubble counter evaporation. One final note, the first kit I received was missing the U-tube, suction cups, and replacement cotton filter. I contacted Revain and provided a replacement which was fine. I returned the first incomplete set for a refund. Missing parts, minimal instructions and questionable valve stats are the only reason for a 4 star rating. Although so far so good. I will update if anything changes. I recommend and hope that these more detailed instructions help explain the setup process better than the minimal instructions that come with the kit.
