This is SunGrow Easy CO2. This is a carbon supplement that helps add the right level of carbon dioxide needed in your aquarium. Plants need carbon dioxide and sunlight to thrive and in most cases your tank isn't in the sun because it would get to much algae. With daily use of Easy CO2 you can get the optimum carbon level. You need to add 5 ml of solution in around 50 gallons of water tank every day. With use of this and your live plants this will aid in preventing algae. This... is clear in color, you can not see it as you pour in the small amount. I have only used this a few days now so I haven't seen a difference, but my fish are still healthy after using. Looking forward to healthy plants as they cost a pretty penny for the tank. This Easy CO2 cost: $7.95 and you can purchase yours here: https://www.amazon.com/…/B01…/ref=oh_aui_detailpage_o04_s00…
