Aquasoil - When does ammonia arrive?

I set up my new 120H four days ago. I moved the two canisters from my 75g to the new tank and have been doing daily 80% water changes and have 250ml of Purigen in one filter. I picked up a new ammonia text kit and so far my ammonia readings have been zero. I've not calibrated the kit so I think that may be the issue, but was wondering if it's too early for detectable levels of ammonia.


Well I guess I shouldn't say they've been zero since how can you really say it's zero based on comparing colors on a card.

 

That was also a thought, but I thought I might have been being overly optimistic.

 

Purigen won't adsorb the inorganic ferts we add such as KNO3, K2SO4, etc. It is fairly specific in the adsorption of DOC's such as NH3/NH4, etc.. I'd not expect 250ml's to remove everything generated by 5 bags of new AS and I don't usually keep it in my filter. I added it to help with the initial large amount of ammonia generated just as the frequent large water changes help.

 

The fish aren't in the tank yet. They're still in a 40 gallon tote waiting to go back home. Large daily water changes seem to be the norm for the first week with AS, at least from what I read it seemed to be.

 

Moved the fish and shrimp into the tank 6 days ago. I did a 50% water change the day before moving them and again yesterday. Fish are happy, shrimp are happy and I'm happy. Ammonia and nitrite were never detectable and I'm attributing it largely to the two mature filters.
