• Count drops against ppm chart: e.g., 10 drops ≈ 400 ppm.
• Coral color loss often occurs below 360 ppm; daily testing helps maintain stability. [oai_citation:2‡Bulk Reef Supply](https://www.bulkreefsupply.com/salifert-potassium-aquarium-test-kit-salifert.html?srsltid=AfmBOorK1wacj2S-C2elyzc3UJOM3fub3GbEdPZZYhdSo3jiy1moDv1s&utm_source=chatgpt.com)
