What's the influence if I stop using the aquarium pure?

- Apr 18, 2019-

For example, the NO3 is 100ppm in the tank for usual, after use aquarium pure, NO3 decreases to 0, if you stop using it, the NO3 just get back to 100ppm gradually.

There's no bad influence on lives whether you use the aquarium pure, but if you use it, it will be beneficial.
