Aqulator is a free aquarium calculator and fish tank manager for freshwater and saltwater aquariums. Get accurate stocking levels and exact chemical doses in seconds. Check tank mate compatibility across 250+ fish species before you buy. Log every water test and watch your parameters trend over time. One aquarium app instead of ten bookmarks. AQUARIUM CALCULATORS 🐠 Stocking Calculator Work out how many fish your aquarium can hold, based on real water volume and the bioload of every species you add. Surfaces the recommended water parameters for your whole stock list. 🔀 Fish Compatibility Checker Check tank mates across 250+ freshwater and saltwater species. Aqulator flags conflicts in temperament or water parameter needs, then explains exactly why a pairing does not work. ⚗️ Chemical Dosing Calculator Get the exact dose for over 450 aquarium products, scaled to your fish tank. Every product carries its own safety warnings. 📐 Tank Volume Calculator Gallons or liters for rectangular, cylindrical, bowfront, or hexagonal aquariums. Shows filled weight too, so you know what your floor is holding. 💧 Effective Volume Set your fish tank's usable water volume once, after substrate and hardscape. Every other calculator then doses the water you actually have. 🧪 RO Remineralization Dial in GH and KH from RO water, whether you keep shrimp or run a planted aquarium. Plus CO2 for planted tanks, heater wattage, ammonia toxicity, substrate depth, aquarium weight, water change volume, and a full unit converter. YOUR FISH TANKS 🏠 Tank Profiles Build a profile for every aquarium you own. Calculators, reminders, and logs all connect back to it, so a fishroom stays as organized as a single fish tank. 📊 Water Parameter Tracker Log pH, ammonia, nitrite, nitrate, GH, KH, temperature, and your own custom parameters. Every reading becomes a chart you can scrub through to spot a problem before it turns into a fish loss. 📷 Photo Journal Watch your aquascape fill in over months. 🏥 Quarantine Workflow Run a medication schedule in your QT tank, then transfer stocking back to the display aquarium when treatment finishes. 📋 Aquarium Planner Plan a build before you spend money on it. Stocking is checked as you go. AI PHOTO TOOLS 🔬 Test Kit Scanner Photograph a test strip or a liquid test kit. Aqulator reads the colors and fills your water parameters in for you. ⭐ Tank Rating Photograph your aquarium for a score out of 10 with specific, honest feedback on what to improve. MAINTENANCE THAT ACTUALLY HAPPENS ⏰ Smart Reminders Schedule water changes, dosing, and filter maintenance against each aquarium. The dosing calculator feeds straight into a reminder with the exact amount already filled in. Turn on personality mode and your notifications arrive written from your fish's point of view. 🔥 Care Streak Every day you log a parameter or tick off a task builds your streak. Milestones get celebrated. It turns aquarium maintenance into something you keep up rather than something you remember too late. 📅 Calendar Export Push a tank's reminders into your own calendar app. PLANS Free covers every aquarium calculator, two tanks, and three reminders on each.
