API Copper Test Kit
The API Copper Test Kit holds its position as the most accessible, budget-friendly copper monitor for hobbyists treating Ich, offering simple colorimetric readings that guide safe dosing decisions. Compared with Seachem's more precise multi-range assay, API trades some accuracy for lower cost and wider availability, making it the pragmatic choice for routine checks during copper-based treatments.

Fluval Sea Hydrometer
The Fluval Sea Hydrometer is a popular, inexpensive tool for quick salinity estimates in marine tanks, making it a common first-line choice when assessing conditions that influence copper dosing for Ich treatments. It delivers fast, no-frills readings at a much lower price than digital refractometers, though it is less precise and more temperature-sensitive than the Hanna HI96801 and should be used as a complementary check rather than a laboratory-grade measurement.
