This drop test is made for aquarists who dose macronutrients and want to check potassium levels instead of guessing. It fits anyone running a planted tank who needs to confirm that fertilization stays in balance, as well as shops and service providers who test water for clients.
Why it matters
- Potassium measurement: the kit measures potassium (K) in aquarium water, so the nutrient dose can be checked against an actual reading.
- Built for the GEN method: potassium is a key parameter in the Growthive Excellent Nutrition (GEN) approach, where the nitrogen-to-potassium ratio is the main control point.
- Read together with NO3: the K result is most useful alongside the NO3 result, because only their relationship shows whether macronutrient dosing is balanced.
- Complete set: each kit includes reagents and the measuring accessories needed for the test, along with instructions for use.
