  • Easy to use and offers excellent value for money. I would definitely buy it again. 🌱
Style: CO2
I am very satisfied with the VIVOSUN CO₂ regulator and emitter system. Installation was simple, and the materials feel sturdy and of good quality. The solenoid valve works perfectly, and the flow meter allows for precise adjustment of the CO₂ flow. Since incorporating it into my hydroponic system, I have noticed improved development and vigor in my plants. ... show more

  • Save yourself some money and get this one, they are all the exact same unit
Style: CO2
This one is the exact same as the $90 Titan. I ordered a Titan CO2 regulator from a hydro shop thinking price=quality, only it started leaking, mostly just at the beginning of fresh tanks, but over 3 tanks it got worse and I couldn't get it to stop. I didn't have time for the run around and the warranty policy offered them any reason to refuse(if you turn the flow up past halfway warranty void). So I decided to 1)order a replacement, 2)tear into the Titan, see what I can see. Being Prime day, the Vivosun was only $32, as I ordered it I was thinking, man, that looks exactly the same as the $90 Titan. I fixed the Titan, better than new(or better than when I got it, it didn't seem new) and got this one today. See for yourself, one has a Titan sticker, one says Vivosun on the tank pressure gauge, other than that...identical. Oh, and this one was new. I would keep it as a spare, but I called Titan to ask a question and the tech warranty'd mine, but asked me not to ever work on them again, didn't even want it back, told me to cut the cord. I mean, cool, but what was I supposed to do in the meantime, that one won't be here for a couple weeks and I've got hungry plants. Get yourself some Teflon tape and seal up every joint you can, your tank will last longer. ... show more

  • Don’t buy this. It’s not quality for CO2 home aquarium.
Style: CO2
I only had this for six months. The only reason I’m taking the time to write this is because this regulator is really low quality junk. I feel a responsibly to warn people. I’m replacing it today after only having it six months. The ball valve leaked. I can deal with that but the plastic is so cheap it stripped even though I was being very careful. The solenoid gets really hot. What ended up making me replace it was after about five days the solenoid would fail and release all my co2 over night. This happened twice. I think it’s dangerous and a fire hazard. It seems like it’s modified for home CO2 aquariums. Idk. It’s junk. You’ve been warned. ... show more

  • it's really good, get it
Style: CO2
For $39, this product is impressive. I just got and hooked it up yesterday. I plugged the solenoid into one of those dial timers that I have my light plugged into. Then I stick the hose through the tiny opening in my tent and let it discharge into a fan. It works perfect! Just make sure you use the teflon tape on tank threads and use the included washer. Use soapy water to check for leaks. Don't hold the plastic meter for leverage when tightening nut, might break. ... show more

  • 1/2 the price of expensive regulators, all the Value
Style: CO2
I have seen a few bad reviews and I would like to set the record straight. 1. With all compressed air products, anything that can unscrew should have Teflon tape (example: the plastic reading tube) now, I understand why they didn't, it unscrew so you can adjust the internal glass meter so it can be read in the position you have the meter. Once you do that, put 4 wraps of any quality Teflon tape around the threads and carefully hand tighten it back. 2. Please please please use the plastic/fiber gasket to attach the tank. It is a necessary piece to prevent leaking of the gas. 3. FINAL AND MOST IMPORTANT STEP!!!!! Get a bottle, water, squeeze tip, trigger spray bottle etc, mix up a decent amount of a very soapy solution (you can test this with a straw, or any smaller tube, dip it in the solution and try to blow bubbles, if you can't add more soap and repeat) and once there is enough soap to retain bubbles, liberally spray or pour the solution over the connection to the tank, the plastic Guage, and all connections with the tank on, regulator dial closed and the solenoid valve open(powered). If the tank/connections are blowing bubbles, you have a leak. If the are no bubbles anywhere, with the above method, you have sealed the regulator to the tank and CO2 should not leak out where it is not supposed to. Steps 2 and 3 should be done everytime you change the CO2 tank. ... show more
