Well it will .... But each ppm
produced use 1 ppm
of ammonia. You have only 0.5 ppm
, the ammonia will only drop by 0.5 .... not enough to be picked up by your test kit.
Give it a day or 2 for the nitrite to spike, then you should see the ammonia falls. <And you would then need to dose some ammonia to keep feeding the nitrifying bugs.>
