You have a low light tank (1WPG), so in your case C02 is not needed. You are dosing Excel so that is a good source of carbon.
Make sure you are keeping your N03/P04 at a 23/1 ratio, so if you have 10ppm/N03 then you need 0.4ppm/P04.
What type plants do you have? Is your tank heavily, medium, lightly planted?
Make sure you have enough fast growers to soak up the nutrients.
What type algae do you have?
Adding algae eating fish/shrimp will help. |
