Field notes
The calculator asks for tank volume, units, parameter, current and target readings, and product; it offers a shareable calculation link and points users to a separate volume calculator. Its estimates assume pure, dry reef- or pharmaceutical-grade chemicals and specified liquid strengths. The FAQ distinguishes bicarbonate from soda ash by both dose and pH effect. The broader logging and AI-advice app is explicitly described as in development, with early access offered by waitlist.
