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 Christina Xiong

At first I hated this thing but then I learned how to use it. So you have two sides: citric acid and baking soda. I figured you needed a citric acid hose constantly submerged in the solution for it to work. It's not like this. As long as you have at least 1 bar of pressure, the system will work without a hose in a citric acid solution. That's how I understood it. I shook the soda side and the pressure shot up, to about 3 bar, then continued to rise throughout the night until it dropped almost to the limit. I thought it would eventually break, but it didn't. I've been feeding my aquarium with CO2 under pressure for about 3 days and it still hasn't dropped to 1 bar. BPS is 1 to 3, which I think is pretty fast for a system like this. switched off at night. The main problem I was chasing was the pressure drop, which made me throw this thing away and spend my money on the right CO2 solution. I finally figured it out and this is where the soda and soda bottles connect to the manifold. Normal orings suck. But technically they are not needed if you stick on enough teflon tape. I think plain white teflon tape will do, but I use yellow teflon tape that's gas approved because... gas. Not all pop and soda bottles are created equal. I've had several large (2+ liter) bottles and one had a crappy thread on it. I switched to a normal Pepsi 2L bottle and Viola, the thread is correct. However, other oversized threaded bottles are fine, so ditch them. Ultimately, I'll probably stick with the usual 2L bottle size. Before wasting the mixture, pressurize the system, submerge it under water and check for bubbles. I hated that thing and now I find it useful.
