But this doesn't explain why I have a ammonia reading of 8 ppm/L. I do treat the water with Ammo-Lock before adding it to the tank. And I use Aquarium Pharmactical chemicals to do the testing.
I just can't understand why the beneficial bacteria isn't breaking down the ammonia. Maybe there's something in my tank that is inhibiting the growth of this type of bacteria.
Welcome to Ammo-lock hell. Yes, it works, just like it says it works, locks up the ammonia, good and tight. Every time, every water change, every week, I'll bet the ammonia just keeps climbing with each water change.
You've lost the cycle, man. That tank is gonna have to come down from that Ammo-lock addiction and get down and dirty with some bacteria.
Personally, I'd do a massive water change and then start using Prime, it will allow the biofilter to get started. Save the Ammo-lock fo one shot deals, transporting fish or major power outages when you know you've lost the biofilter anyhow.
