Store description excerpt
Stop doing fertilizer math by hand for your planted tank. FertFlow tells you exactly how many grams of each compound to dose today based on your tank size and dosing method. Every planted tank hobbyist using dry fertilizers faces the same problem: KNO3, KH2PO4, K2SO4, CSM+B — each compound has different molecular weight ratios, contributes overlapping nutrients, and requires different amounts depending on your tank volume and method. One wrong calculation means nutrient imbalance or algae. HOW IT WORKS 1. Enter your tank volume and select your dosing method (EI or PPS-Pro) and tech level (High-Tech or Low-Tech). 2. FertFlow calculates the exact grams and teaspoons of each compound for today's dose, based on published EI and PPS-Pro target concentrations. 3. Open the app each day to see your dose — Macro Day, Micro Day, or Water Change Day — and mark it done. It takes 30 seconds to set up. No account required. TODAY'S DOSE Your home screen shows exactly what to add today. EI method alternates macros (Mon/Wed/Fri) and micros (Tue/Thu/Sat) with a Sunday water change. PPS-Pro shows daily doses of all compounds. Each compound displays grams and teaspoons. CUSTOM CALCULATOR Need a one-off calculation? Select any compound, enter your target ppm, and get the exact dose for your tank. The calculator shows all nutrient contributions — for example, how much K you get from your KNO3 dose. SUPPORTED COMPOUNDS KNO3 (Potassium Nitrate), KH2PO4 (Monopotassium Phosphate), K2SO4 (Potassium Sulfate), MgSO4 (Epsom Salt), and CSM+B Trace Mix are built in. Pro users can add custom compounds. PRO FEATURES Upgrade to Pro for deeper control: - Multiple tank profiles (up to 10) - Unlimited dose log history - Custom compound definitions - Daily dosing reminders (notifications) - Water change day tracking - Weekly dose summary report PRIVACY FIRST All data is stored locally on your device. No account, no tracking, no server. Your tank data never leaves your phone. FertFlow is a dosing calculator and scheduling tool for planted aquarium hobbyists. Always test your water parameters and observe plant health. This app provides general guidelines based on published dosing methods (EI, PPS-Pro). Individual results vary.
