Helped out friend last night by giving him one of my media pads to get started. This morning tested my water and its showing a low trace of ammonia. How long will this happen and when will my tank get back to normal. Should I change water now.
If ammonia levels go above 0.25 PPM, then you need to change water.
How are you testing?
At the moment, you don't have quite enough bacteria to cope with the load, but in my experience, things should stabalize fairly quickly as the bacteria colonize the new pad. Just keep monitoring your ammonia and nitrites over then next few days and change water as required.
Sure everything will be fine.
