Test strips are junk and less than 70% accurate. You have to use the liquid kits. If these are indeed test strips your using then you really don't know whether your tank is cycled. Test strips are very flakey, sometimes they throw you onto the opposite end of the spectrum. I have both strips and the liquid, I get far better readings with the liquid.
Salifert kits are the most accurate
