Ok thx how often do u test ur water like every month
It's also very important too to test aquarium when you have fry to raise or juvenile fish that are still growing. I personally test frequently in either of those situations.Tbh I test my aquariums occasionally when adding new fish to one of them or if I notice a change of behavior of fish. I do consistent water changes and filter maintenance. Also test more If setting up a new aquarium and waiting for cycle to complete.
