Whether you’re new to the hobby or a seasoned aquarist, AquaDeck helps you organize parameters, upkeep, livestock, spending, and memory — so your tanks stay healthy and your logs stay effortless. AI SPECIES IDENTIFICATION Snap a photo to identify fish, corals, and invertebrates. Review confidence-ranked matches, open care info from the species catalog, and add livestock to your tank inventory in a tap. TRACK WATER PARAMETERS Log pH, ammonia, nitrite, nitrate, salinity, temperature, and any custom parameter you define. Browse history at a glance and spot drift before it becomes a crash. MAINTENANCE SCHEDULER Schedule recurring care — water changes, filter service, dosing, and more — and get push notifications while the app’s in the background so tasks don’t get forgotten. PHOTO TIMELINE Document your aquascape over time — coral growth, plant fill-in, and layout changes — in one visual timeline. SPECIES INVENTORY Track what lives where: fish, coral, inverts, plants — additions, notes, and care context per tank. DOSING, EQUIPMENT & PLANNING Log dosing templates, track equipment and service dates, plan water changes, and use built-in aquarium calculators when you need quick numbers. EXPENSE TRACKER Record livestock, gear, food, and supplies — see totals per tank and prepare summaries when you’re ready.
