Know what's in
your water.
Upload a photo of your tank, pond, or reef. AI analyzes water color, clarity, algae, and surface conditions — returning a health score and plain-English findings in seconds.
Upload a photo — get a score
Photo your tank, pond, fish, algae, or plants. Select your scan type, add optional test kit readings, and get an AI-powered diagnosis in seconds.
The water shows signs of elevated algae bloom activity and mild discoloration in the green-brown spectrum. Surface foam is visible near the edges. These conditions are consistent with nutrient runoff in warm weather. Swimming is not recommended. Fishing may continue with caution.
-
Algae & Bloom Detection 62 / 100Moderate surface bloom visible. Green discoloration across approximately 15–20% of visible water surface. Consistent with cyanobacteria presence — avoid direct skin contact.
-
Water Color & Clarity 74 / 100Water hue is in the acceptable green-blue range. Slight turbidity detected — visibility estimated at 60–80cm. Not alarming, but below ideal clarity thresholds.
-
Surface Debris & Foam 70 / 100Organic foam detected along the glass. Pattern is consistent with decomposing plant matter rather than detergent or chemical contamination. Monitor if foam increases.
-
User Observations 65 / 100Mild odor reported. No dead fish observed. Recent normal weather reduces runoff risk. Observations are factored into the overall score weighting.
Three steps to water clarity
No lab. No equipment. Just your phone camera and thirty seconds.
Snap a photo of your tank or pond — or upload one from your camera roll. The AI works with any angle or lighting.
Tell us what you noticed: any odor, unusual sightings, or recent weather. These observations sharpen the AI's analysis.
WaterDoc returns a 0–100 health score with plain-English explanations of every finding — and a clear recommended action.
Six things WaterDoc reads
Four scan modes, each with weighted sub-scores. Point the camera, pick a mode, get a diagnosis built for aquarium and pond keepers.
-
Water Clarity & Color Water Scan
Reads hue, cloudiness, and discoloration. Detects bacterial blooms (milky white), chemical issues (vivid unnatural color), new tank cycle turbidity, and tannin tint — each scored and explained.
-
Algae Detection & Identification Algae Scan
Identifies algae type — black beard (BBA), brown diatoms, green spot, cyanobacteria, green water — and pinpoints the likely root cause: excess nutrients, low CO2, or light duration.
-
Surface & Substrate Condition Water Scan
Checks for oily surface film, detritus accumulation, visible waste buildup, and signs of poor filter flow — conditions that degrade water quality before parameters spike.
-
Fish Health Screening Fish Scan
Scans body, fins, eyes, and posture for ich (white spots), fin rot, popeye, velvet, ulcers, bloating, and clamped fins. Returns a health score with suspected condition and urgency level.
-
Aquatic Plant Health Plant Scan
Diagnoses nutrient deficiencies from leaf symptoms — nitrogen (overall yellowing), iron (new leaves pale), potassium (holes and crispy edges), calcium (deformed new growth) — and recommends a fix.
-
Observations & Test Readings User Input
Odor level, unusual sightings, and recent conditions are factored into the score. Numeric test results (pH, ammonia, nitrite, nitrate) are cross-referenced against your species' safe ranges.
0 – 100. Weighted. Actionable.
Every scan produces a numeric health score. Each band triggers a specific recommended action — from "your tank is thriving" to "immediate intervention required."
