Review on 🐠 Enhance Your Aquarium with the DIY CO2 Generator System Kit: Pressure Gauge, Safe Valve, Air Adjuster - A Must-Have Fish Tank Plant Necessity! by Joy Owens

First I have a small complaint about it. There is no bubble counter in this system so it's impossible to tell how two regulate this, I use two, I use sugar and yeast as you can see in the last picture, it's a great alternative and both ways are great economical, but this citric acid is much more reliable. I don't have much money so I need cheap alternatives. I just hooked this up and 1 bubble every 5 seconds lasts 80 days. i go 3 two 5 every 5 seconds works really great and great results it's great. Haven't seen any results yet, I just hooked it up. but my girlfriend gets sugar on sale for $2$ a bag. and by no means do sugar, water, and yeast come close to two of that system. I think you can use vinegar instead of citric acid. but a box of baking soda goes for 2 times and citric acid in containers if you can keep two veggies for $1 green and it's almost 200 grams so $3 is a little cheaper a 5 lb bag is $14 and will do for that last 3 be easy years. and you can't smell the alcohol from the gas in the sugar water fart. you have to see two. but it has been working for 2 days, the pressure is good, no problem. and the last photo is the first week of washing, I have 2 more after this week, these plants double in girth. Very good product had a big problem connecting two bubble counters it should be with one.
