Yesterday, I put my first two fish, a male red wagtail platy and a female gold dust Molly into a new 10 gallon tank. In addition to plants, rocks, heater, filter, etc., i put a "seachem ammonia alert" system into the tank. Today, the water seems partially cloudy, and the ammonia level reads less than 0.02 ppm. My question is: how long should it take for the cycle to start (ammonia spike)? I have two live plants in the tank if that helps.
