Hi ,

need some help on this issue.
i have set up two 1 ft CRS tank .
First tank is over 2 years and stable ( PH 5.5) , shrimps breed and grow well.
Second tank set up about 2 months back , ( PH 5.5) , shrimps didn't do well and some died.

water change for both tanks are 10% weekly.
However , i realised that the NH4/NH3 test for first tank is level 8 !! and second tank is level 0 .

Am i right to say that tank 1 is full of ammonia which is bad for shrimps but how come they still doing well ??

Thanks
