Ammonia Cycling Calculator I need to use this Ammonia cycling calculator to figure out how much I need to add to have around 1 ppm of Ammonia. Ammonia Cycling Calculator I have a few questions on the information I have to enter in. For system parameters I'm assuming that it means the parameters of my tank right? What's the system salinity? For the solution, they have a slot for temperature, do I have to measure the temperature of my Ace Hardware brand Ammonia? Will it ruin the probe of my digital thermometer? For the results section, what do they mean by density? It will be on the bottle of ammonia?
