Aquarium Co-Op Easy Green
For most hobbyists Easy Green is the easier, better-value pick. It is a true all-in-one with nitrogen, phosphorus, potassium, and micros, so one bottle and a pump-per-10-gallons routine feeds most low-tech tanks without mixing anything. Keepers like that it takes the guesswork out of dosing, which is exactly what a busy planted tank owner wants.

Here is which fits how you want to dose.
