The Nutrient Tightrope
In high-tech planted aquariums, water is not just a medium; it's a chemical soup that requires constant balancing. If you are dosing fertilizers based on a "weekly schedule" rather than actual test results, you are flirting with disaster. An excess of PO4 (Phosphate) breeds algae, while a deficiency in K (Potassium) leaves your plants with pinholes. The difference between a lush underwater garden and a green slime nightmare is your ability to track the consumption rates of your tank. You shouldn't be "adding drops"; you should be managing a nutrient budget.
This template is a digital технічний cockpit for the aquascaping chemist. It moves beyond the simple "water change" log and captures the granular chemical analysis of every Water Source and every dosing event.
The Dosing Matrix
The strength of this system is its separation of macro and micro nutrients. It doesn't just ask "did you fertilize?"; it breaks down the specific input of Nitrogen, Phosphorus, and Iron Product. This allows you to fine-tune your dosing regime based on the specific uptake of your flora. If your red plants are fading, you can look back at your Fe Amount (ml) logs and correlate them with your Fe (goal: 0.2-1.0 ppm) test results. The system forces you to be deliberate about every milliliter you add to the water column.
The automated CO2 calculation script is a critical safety feature. By cross-referencing your pH and KH (Carbonate Hardness) inputs, the template instantly calculates your CO2 ppm. This prevents the "gas-off" that suffocates fish or the low levels that starve plants. You have a real-time safety check every time you test your water parameters.
The Testing Feedback Loop
The ultimate value of this system is the feedback loop between testing and dosing. You can see the direct impact of your Micronutrients Product on your dGH (General Hardness) over time. You stop reacting to algae blooms and start predicting nutrient depletion. You move from a "reactive" hobbyist to a proactive water chemist, ensuring that every Date & Time entry builds a clearer picture of your tank's unique biological engine.
