Review: Best DIY C02 out there! Results are in the pics! - (Before and after pics of the tank this system is on after only a few weeks) After about 5 years, I finally decided to go for it and pick up a CO₂ kit for my aquariums. After a few different diy kits, this is by far the best. The setup is surprisingly simple — everything comes in the box, and it only takes a few minutes to put together. The DIY fill with citric acid and baking soda is easy and much cheaper than buying pressurized refills. The build quality is excellent. The upgraded 304 stainless steel tank feels heavy-duty, with a polished finish that actually looks great sitting next to the tank. The compact solenoid + bubble counter design is one of my favorite parts: it’s easy to fill, reduces the risk of leaks, and makes maintenance way less of a headache than other setups. Safety is another big plus. The dual safety system with both a manual shut-off and automatic pressure relief valve gives real peace of mind, especially for new users like me. And the included accessories (diffuser, tubing, suction cups, etc.) mean you don’t have to hunt down extras. Overall, this kit is a perfect balance of high quality and user-friendliness. If you’ve ever wanted to try CO₂ but thought it would be too complicated, this system makes it easy, safe, and effective. My plants have already shown noticeable growth, and I couldn’t be happier. Highly recommended.
Review: Works as intended - Great product. I really enjoy it. Simple to set up. Ive had it running for a fews now it does exactly what is needed. Please note you need to buy the citric acid and the sodium bicarbonate separate from this item.

### ⭐⭐⭐⭐⭐ good to have. saves money.
*by N***H on December 28, 2025*

works great, though my problem now is getting it to flow through out the tank and not just escaping out the tank with default dispenser.
