Defussers

There's a run down for the DIY CO2 reactor on my site(it is free to see and view this item) that cost about 3$ plus the cost of a small power head (9-10$). This will allow you to shut off the CO2 at night when you do not need it adding more safety for your fish. It will also maximize the usage of DIY CO2.
