Product potencies come from each manufacturer’s published directions and technical pages (Aquaforest, ATI Aquaristik, Brightwell Aquatics, Bulk Reef Supply, Continuum Aquatics, DIY recipe, ESV, Fauna Marin, Kent Marine, Korallen-Zucht, Microbe-Lift, NYOS, Polyp Lab, Red Sea, Seachem, Triton Lab, Tropic Marin, Two Little Fishies). Where a maker publishes a concentration rather than a dose, the potency is derived and marked as such. DIY chemicals are computed from their chemical formulas. Every product page lists its sources.

Consumption is measured from your own tests: the app adds back everything you dosed and every water change, and fits a trend to what is left. Daily rise limits (for example no more than 1 dKH of alkalinity a day) follow widely used reef chemistry guidance and are applied to every recommendation, including the AI advisor’s.

Dosing guidance is calculated from manufacturer data and your own test results. Test kits vary and products change; always confirm with a fresh test before a large correction, and follow the product label.

Your tank log stays on your device unless you sign in to sync it. If you sign in, your log is stored in our database and is visible only to you. When you ask the advisor a question, your tank’s recent log is sent to our server and to Anthropic to generate the answer; it is not used to train models. Buy links pass through our server so we can send you to your local Amazon store; we count clicks per product but do not store your address.
