It reflects the available research, not my own product testing. See how we research our picks →

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.

Both dose your planted tank, but they are built for different keepers. Easy Green is an all-in-one that includes nitrogen and is meant to be simple; Seachem Flourish is a trace/micro supplement that many pair with separate nitrogen and phosphate. Here is which fits how you want to dose.
