Which parameters must be tested separately during new tank cycling: a step-by-step guide

During tank cycling, ammonia nitrogen, nitrite and nitrate must be tested separately, while TDS, conductivity, salinity, hardness, turbidity, UV254, TOC, COD and others can be screened and trend-monitored with Water Detective 4. This article provides a reproducible step-by-step guide covering sampling, measurement, interpretation of results and an action checklist.

What TDS readings can and cannot answer

TDS is the most frequently displayed indicator in water purification products, and also the easiest to misread. This article is aimed at smart small-appliance brands, product managers and hardware engineers, and, combined with the multi-parameter screening capability of AtomBit Water Detective 4, presents the questions TDS can and cannot answer, reproducible sampling steps, common interferences and an action checklist to help teams use TDS in the right places in filter management, user experience design and technical communication.
