Latest release
What’s New
Your tank health score now reacts to acute danger. A measured ammonia, nitrite or chlorine spike in a stocked tank lowers your score straight away and shows up as an insight. Until now, a tank with dangerous ammonia could still read 85%. A tank still cycling with nothing in it isn't penalised — there is nothing to harm yet. Choose what each tank tracks "Manage parameters" adds ammonia, nitrite, chlorine, copper or salt to any tank. Nothing changes unless you turn them on. On a young tank, ammonia and nitrite move to the top, where you need them. A coach that reads the new numbers It works out how much of your ammonia is in the toxic free form at your pH and temperature, never suggests copper where invertebrates live, and tells chlorine in your tap water apart from chlorine in the tank. Finer input Phosphate and pH in smaller steps, ammonia and nitrite to three decimals. The line between safe and harmful sits at 0.25 ppm — now we won't round your reading across it. Also in this update Your app stays on the aquarium you last selected, including after a restart. Plus the usual round of fixes and refinements.
