Carbon is the key element to beautiful and healthy plants. The best way to supply your plants with carbon is through carbon dioxide (CO2). But not everyone wants to break the bank on expensive pressurized CO2 systems. Fortunately, UNS has released an amazing product to provide planted tanks with CO2 for a fraction of the price. The UNS Nature Bottle CO2 is finally back in stock after being backordered for half a year.
