Sera Ammonium/Ammonia-Test

2Hr Aquarist Commentary: Sera and Salifert both produces reliable ammonia test kits. When using, remember that results take a while to appear; colour change is not immediate. A tank should always measure 0 on ammonia tests as long as there are no recent spikes in ammonia for example, due to heavy feeding. Any positive reading indicates that the bio-filter is still not fully mature (that tank cycling is not yet complete). It also serves as a proxy indication that organic waste in the tank is not being processed efficiently, which is one of the key triggers for algae.
