Hey guys, I've seen everyone saying that 0 Nitrates is a sign of a uncycled tank...

My current params are

0 Ammonia
0 Nitrite
0 Nitrate
7.6 Ph

The tank has been stocked for over 3 months, 1 of 4 filters replaced (saved biomax that I had used in place of carbon)

The tank is planted (i'd say medium, its no forest, but as you see in my sig I have a lot of plants)

So do I have a problem, or is 0 nitrates possible...

*note I haven't done a water change in around 10 days (just seeing if I could get a reading), I have only topped off the tank occasionally from evap
