It's ok if the kit doesn't detect the change from the ammonia blocker. Just take a reading, if the ammonia level has gone up, do a big water change and then use whatever ammonia binder you have handy. Next time you test, you will expect the ammonia level to be half of what it was, and just trust that the amount the bottle says it neutralizes is neturalized.
