Ways AquaPulse can help
Find a starting point for your aquarium—whether you're checking water, planning a setup or worried about a fish.
Right now
- Interpret my water readings You've just tested your water and the numbers don't mean much on their own — see what each reading actually indicates.
- Something looks wrong right now A fish is behaving differently — use Emergency Diagnosis for a calm, ranked starting point on what to check first.
- Understand a specific symptom Gasping, hiding, flashing, clamped fins — browse the Fish Symptoms hub to find the one that matches what you're seeing.
Setting up an aquarium
- Not sure where to start Freshwater or saltwater? See the real cost, maintenance and learning-curve differences before you buy anything.
- Starting a new freshwater tank You're setting up an aquarium and want to get the early weeks — and cycling — right.
- Starting a new saltwater tank Salinity, live rock, protein skimming and cycling — the marine equivalent of the guide above.
- Starting a new planted tank Substrate, lighting, CO2 safety and silent cycling — setting up with live plants from day one.
Keep your aquarium stable as temperatures fall
- My tank is colder than it should be Confirm the reading, check what your livestock need and avoid sudden temperature changes while it recovers.
- My heater isn't keeping up Work through placement, settings, room temperature and flow before deciding it has failed.
- Check my heater is big enough Get a starting wattage range using the coldest temperature your room reaches.
Planning ahead? See what to do in a power cut, and where heater checks fit in a maintenance routine.

- Choose what to add to your tank Care requirements, compatibility and common mismatches for specific fish, shrimp, snails and plants — browse the Species hub.
- Work something out for your tank Water changes, tank volume, heater wattage, dosing and more — calculators for freshwater, planted and marine setups.
Ongoing care
How it works
From aquarium information to a clearer next step
The website helps you understand the essentials. AquaPulse brings your recorded readings, livestock and care history together, helping you make sense of your own aquarium over time.
-
Understand what your readings mean
See a clear, plain-language explanation of your water — not just a number, but what it means for your tank.
-
Get a calm, relevant next step
A practical suggestion for what to do next, based on your own tank rather than a generic checklist.
-
See the pattern, not just today's number
Each reading adds to a clearer picture of your aquarium, so a slow drift is easier to catch early.
-
Keep your tank's history in one place
Come back after a water change or a new addition, and see what's actually changed.

Your aquarium's story
Every aquarium has a history worth remembering
Aquariums change slowly — a cycle completing, a new care rhythm settling in, livestock finding their place. AquaPulse helps you notice that progress and keep a record of it, so caring for your tank feels like continuing a story, not starting over each time.
- See how your readings and care routine have changed over time
- Keep a record for each tank — freshwater, planted, shrimp or reef
- Notice stability and progress, not just problems
Guardian
A careful companion, not an alarm system
Guardian looks at the aquarium information you give it — readings, routines and history — and helps you understand what it means. It can't watch your tank for you, and its guidance is only as good as the information behind it. Think of it as a second pair of eyes, not an automatic monitor.
What Guardian can help with
- Water quality logging and interpretation
- Freshwater, planted, shrimp and reef aquariums
- Tank cycling guidance
- Livestock compatibility and ecosystem planning
- Maintenance reminders and routine support
- Plain-language explanations of what your readings may mean
Two ways in
By topic, or by species
We're writing clear, practical explanations for the questions fishkeepers ask most — from water chemistry to a fish that's behaving differently.
Knowledge Centre: water quality and aquarium chemistry (ammonia, nitrite, nitrate, pH, hardness and the nitrogen cycle), fish health and behaviour (gasping, hiding, appetite loss, white spots, swim bladder problems and more), and dedicated marine & reef and planted aquarium clusters (salinity, reef chemistry, coral health, CO2, lighting and fertilising) — organised by what you're trying to do, with search built in.
Browse the Knowledge CentreSpecies hub: care requirements, compatibility and temperament for specific fish, shrimp, snails and plants — and the common mismatches generic pet-shop care sheets get wrong. It prioritises species that are popular but poorly served elsewhere, not a complete database of every species in the hobby.
Browse SpeciesNot sure what a reading means? The Water Check page explains what ammonia, nitrite, nitrate and pH readings actually indicate — no download needed. Recording your own readings and tracking them over time is what the AquaPulse app adds.

Built from the experience of keeping aquariums, for everyday fishkeepers.
AquaPulse was built to solve a simple problem: most aquarium apps focus on recording data, while fishkeepers often need help understanding what that data means. Our goal is to help aquarium keepers make better decisions and enjoy the hobby with greater confidence.
