PondIQ — know your water before your fish do

A pond tells you when something is wrong — but by then it's usually been wrong for a while. Pond IQ keeps the numbers, spots the drift, and answers the questions a good aquatics shop would, using your pond's own data.

🧪

Water quality

The tests you already do, finally somewhere useful — with a second pair of eyes on every result.

  • pH, ammonia, nitrite, nitrate, KH, GH, temperature & oxygen
  • Instant safe-range warnings the moment you save a test
  • Full history, so a slow drift is visible before it's a crisis
  • Works with whatever test kit you already use
🐟

Fish & feeding

From a named koi collection to a shoal of goldfish — stock, growth and feeding in one record.

  • Stock register — individuals or batches, any species
  • Length & weight measurements with growth over time
  • Feed log — what, how much, how often
  • Treatments & dosing recorded against the pond
  • 🧠 AI Pond Advisor — stocking, feeding & companions, with follow-up chat

Planting, wildlife & kit

The living pond and the machinery that keeps it that way — both looked after.

  • Pond plants — marginals, floaters, oxygenators, deep-water
  • Wildlife sightings log — frogs, newts, dragonflies, birds
  • Pumps, filters & UV with service reminders
  • Maintenance log — water changes, netting, winterising
🧠 The AI Pond Advisor uses YOUR pond's numbers
Not generic pond-keeping advice. It reads your pond's volume and filtration, the fish actually in it, your latest water test and your real feeding history — then tells you if you're under or over stocked, whether you're overfeeding for the season, and flags any compatibility concerns between your species. Then you can ask it anything.
