Homemade CO2 injection system and air stone

Here is my homemade CO2 system for my planted aquarium. I used a 1.5 litre bottle for the reactor which contains water, sugar and yeast. The second bottle acts as a bubble counter and also stops anything unwanted coming through from the reactor. I installed a check valve just before the tank as my first attempt syphoned water from my tank when I unscrewed the reactor. I used a filter tip to act as a diffuser so that the CO2 can be absorbed into the water.
