This brand works so much better if you need a regulator that works well get this one! Read more

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. Read more

haven't had a single issue with it since setting it up. EDIT: Been using it for about 5 months now and it is pretty inconsistent. But I can't tell if this is because that's inherent to single gauge regulators, or just this specific regulator. Some days it turns on and the co2 if flying out way way too fast. Some days it turns on and it's barely putting anything into the tank. Some days it's perfect. From what I've found the issue has to do with the pressure inside the co2 tank vs. the co2 pressure in the aquarium. When the two aren't in equilibrium, the output will be inconsistent. This is what makes dual gauges better. Spend the extra dough, get a dual gauge first is my official statement. Read more

They will arrive used, opened and missing components. I’ve ordered two. One worked. Both had missing parts. Not ordering these again… I suggest you don’t either despite the low price. Very poor quality control. Read more

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. Read more

Needed to pressure test a mini split install, and it did the job of metering the right pressure out. I'm happy with it. Read more
