Did you acclimate it to new tank as if it were just purchased? Also was there a variance between both tank levels ?
Ideal values are;
Moderate light and water flow
Temperature 77-79
Ph 8.1-8.3
Salinity 1.025
The ammonia, nitrate at zero seems odd. I would suggest taking a water sample to a trusted LFS and have them test water and verify the parameters and to compare with yours
I thought the same thing. The OP stated that he had ZERO Ammonia using API. In my experience, API NEVER gives a ZERO reading where ammonia is concerned.
