Breeder Tank Ammonia Spike

So I tried to please the pair by feeding them from frozen blood worms, dry blood worms, to frozen beef hearts. I even got GarlicGuard to help increase their appetite. But the pair are very slow eaters. Maybe they are still getting used to their new home. They never finished any of the food I give them. In the end I have to vacuum out the leftover, either give it to the big tank or throw away. Any waste I see at the bottom was vacuumed out right away. Then one day, the water seemed cloudy and I decided to test the breeder tank water. Ammonia is light green. My first thought is to use the Nitra-Zorb bag insert in the HOB filter. Nitr-Zorb suppose to help remove ammonia and nitrate.

     The following day, I tested the water again and I still see some ammonia. I changed out 3gal of water and waited for the next day to test again. Still light green. So I decided to use Ammo-Lock to detoxify the ammonia. That was when the problem got worse.
     Ammo-Lock detoxifies Ammonia temporary for 24 hours so that the bacteria can catch up to eating up the ammonia. Ammonia will still test positive and results even more green on the Ammonia test. I put in some Ammo-Lock every other day but the test keeps showing dark green! Dark green is off the chart and is considered extremely toxic! How could this be? The ammonia is testing worse after it being detoxified by Ammo-Lock? I did an 80% water change; the next day ammonia still tested dark green! I get really worried because I cannot figure out the cause. Yet I am running out of ways to possibly solve this problem.

On top of that the PH dropped to 6.0! If the water is too acidic, the good bacteria will have a hard time to accumulate. I over dose the tank with stability, hoping to speed up the biological filter, but still the ammonia test still show dark green.
     This went on for 4 days. The pair somehow seemed normal. They swim normal and breath normal. How could this be when the Ammonia is tested 8.0? Base on the result, there is more than enough ammonia to wipe out the whole tank!
    So I did a little late night research on Ammo-Lock. Someone had the same problem and the cause of the false reading is Ammo-Lock!  Ammo-Lock bonds to the ammonia and converts it to a less toxic version. It is so potent, it will always yield the false dark green reading on the Ammonia test. What can I do to get rid of both Ammonia and Ammo-Lock? To get my true reading again?
    There is one very last thing to try.....change 100% of the breeder tank water. This is the only way to get rid of the Ammo-Lock trace.  But that means I will have to  recycle the tank again. I overdosed the tank with bacteria hoping it will speed up cycle. In the meantime, I have to move the pair to the big tank where the water parameters are safe. I have some hesitant moving the pair; I don't want to shock them, but  I cannot have them go through the nitrogen cycle. Of course safety is priority.  The pair was moved to the display tank and the breeder tank started fresh with aged water and was overdosed with Tetra SafeStart.
