Water parameters all at zero.

[skargo2009]

I want to know if it's normal for all the water parameters to be at zero in a heavily planted tank. I've had the tank for 6 years and I've had the plants in it for about 7 months. My ammonia is at 0, nitrite 0 and nitrate 0.

The tank is overstocked as well so I would've thought something would be above zero.

Heavy planted is subjective. It is possible to have enough plants in a tank eat up all the Nitrate.
