Question

Good night I was wondering 😊 f easy green should be used after a water change or just weekly for a small and low light planted tank.

How often are you doing water changes, and are you doing them because of nitrates or for another reason? And how small is the tank? All of that might matter.

In general, it makes sense to add fertilizer after doing a water change instead of before doing one. That way, the plants have time to use the ferts before water is removed from the tank during a change.

But there are a lot of variables and more info is better for making recommendations.

i would certainly work in fertilizing after a water change, as with a water change you have just removed water/nutrients from the the tank, so it makes perfect sense to do it shortly after a water change.
