Easy to setup and adjust. Consistent co2 delivery. The relay does run cold too, a great option over the cheaper Chinese products that can run very hot.
I read endless reviews of other regulators where reviewers returned 80+ % because they don't allow consistent, predictable setting of the bubble count. But I knew better. I had to return one that was half the price but the solenoid never opened the CO2 flow. This one worked out of the box. No leaks, less than five minutes to set up, and setting rock solid. They should all be this simple. But they're not. Get this one.
I purchased this product for my 45 gallon heavy planted aquarium. The shipping was faster than I expected and the quality of the regulator is what I was hoping for. It was very easy to install and set up. I will definitely be ordering another for my next 75 gallon build.
Love this regulator! Set it and forget it dont need to constantly adjust the needle valve and shipping was extremely fast will be buying another for my 75 gallon I'm currently setting up! P.s. customer service is also excellent I had a question and they got back to me within 24 hours. Plants are happy as well!!!
I purchased this regulator for my med/high light 75 gal planted tank. It was easy to set up and adjust. I had asked my engineer ex-husband to help set up to prevent my making a mistake, then felt foolish after seeing how simple it was. The regulator itself is well-made (said the engineer :) and was packaged carefully. I'm glad I spent a tiny bit extra for this quality product.
I read a ton of reviews on Amazon and it seemed like I could spend a little less on something that received mixed reviews...but why??
