For high-tech planted tanks

Your aquarium,
run on instruments.

AquaGuru computes each tank's true net water volume — after substrate and hardscape — and derives every fertilizer dose, water change and stocking decision from it. No guesswork. No spreadsheet. No test kit required.

Six instruments, one panel

Everything a serious tank needs. Nothing it doesn't.

Every module reads from the same source of truth — your tank's net water volume — so the numbers always agree with each other.

Multi-tank management

Every aquarium gets its own profile — dimensions, substrate depth, hardscape load — and an automatically computed gross and net volume.

Smart dosing

Daily and weekly schedules with exact millilitres scaled to your net volume. Mark a dose done and it stays done — until tomorrow.

Water-change assistant

Tells you exactly how many litres to change and how much conditioner to add — computed from net volume, never from the label's rule of thumb.

Parameter trends

Log pH, kH, gH, NO₃, PO₄ and TDS over time. No test kit? Estimate mode keeps the app fully functional with sensible modelled values.

Ferts & liquids cabinet

One global shelf of every product you own. The assistant only recommends what's in your cabinet — never a product you'd have to go buy.

AquaAI diagnosis

Photograph an algae outbreak and get a species-level identification with probable cause and a fix plan — using only products you own.

One number drives everything

Net volume is the root variable.

A "60-litre" tank never holds 60 litres. Substrate displaces water. Rocks and wood displace more. Dosing to the label's volume means chronically overdosing your actual water column.

AquaGuru subtracts substrate and hardscape displacement to find the litres that are really there — then every dose, conditioner amount and stocking call is derived from that single number.

// cm → litres gross = (w × h × d) / 1000 subLoss = (w × d × substrate) / 1000 hardLoss = gross × 3–9% // hardscape net = gross − subLoss − hardLoss // everything derives from net weeklyWC = net × 30% condMl = weeklyWC / 40 doseMl = ƒ(net)
AquaAI

An assistant that actually knows your tank.

Most AI chat gives generic forum answers. AquaAI reads your tank's real context before it says a word.

  • Full tank context

    Specs, net volume, dosing program, equipment and your test history — or estimates — are injected into every conversation.

  • Only what you own

    Recommendations come exclusively from your ferts & liquids cabinet, with doses computed from your net volume.

  • Photo algae diagnosis

    Snap the outbreak; get the species, the likely cause in your setup, and a step-by-step fix plan.

ESTIMATE MODE

No test kit? No problem.

AquaGuru stays fully functional with zero test data — trends, advice and AquaAI all fall back to modelled estimates based on your tank's age, stock and dosing.
