First, the nitrate tests in the basic kit and the master reef kit are identical. And somewhat unreliable in that various external (or not nitrate) factors can throw off the readings. But in the cycle , so what. 10, 60, who cares. After the cycle is done massive water changes will lower it and, for the most part, correct the chemical imbalances throwing off your readings.
Second, rule of thumb is 4ppm ammonia converted completely to nitrate in 24 hours, with no residual nitrite either, means your DONE! Check it, you may be there.
