KoiQuanta Disease Treatment Tracker: Log Every Symptom and Dose
Misdiagnosed koi diseases account for 35% of treatment failures and unnecessary fish deaths. You're treating for ich when it's actually Costia. You're treating for bacterial infection when the gills are packed with flukes. The treatment doesn't work because it's targeting the wrong thing, and meanwhile the actual condition is progressing.
KoiQuanta's disease treatment tracker connects symptoms to treatment plans automatically. The integrated symptom checker links every disease entry to a calculated treatment dose and follow-up schedule. Not so you can skip good diagnosis, but so you have a structured system that forces complete observation before you commit to a treatment path.
TL;DR
- KMnO4 for a fish that actually needs an antibiotic.
- You confirm your pond or tank volume (pre-filled from your stored profile) 2.
- The dose calculator runs for the selected treatment at your current water temperature 3.
- The calculated dose is presented with safety ranges and notes on temperature-dependent adjustments 4.
- For formalin, the dose adjusts downward at water temperatures above 22°C to account for the oxygen depletion risk.
- The re-treatment alert appears on the correct day based on your logged water temperature, not just a fixed 7-day interval that ignores the fact that parasites develop twice as fast at 28°C as they do at 18°C.
- You've done more in 3 minutes than a health log does in 30.
The Problem With Unstructured Disease Management
Most hobbyists manage koi disease the way most of us manage car problems: something looks wrong, we search online, we find the most common cause of that symptom, and we treat for it. Sometimes we're right. Often we're not.
The problem isn't that hobbyists are careless. It's that koi disease symptoms overlap heavily. A fish hanging at the surface with clamped fins and reduced feeding behavior could be:
- Gill parasites (flukes)
- Costia or other ectoparasites
- Bacterial gill disease
- Low dissolved oxygen (not disease at all)
- Ammonia toxicity (not disease at all)
- Early KHV or SVCV (notifiable disease)
Treating each of these with the same approach, or treating for one when another is the cause, wastes time and money at best, and kills fish at worst. Formalin for a low-oxygen event. KMnO4 for a fish that actually needs an antibiotic. Salt when the real problem is ammonia.
KoiQuanta's treatment tracker doesn't diagnose for you. It structures your symptom collection and walks you through the differential so you're making a more informed decision before committing to treatment.
Core Features
Symptom Logging and Differential Diagnosis
When you open a new disease entry in KoiQuanta, you start with symptoms. The tracker prompts you through:
Water quality status: What are your current parameters? Ammonia, nitrite, dissolved oxygen, temperature? This immediately flags whether the symptoms might be koi pond water quality tracker-related rather than disease.
Behavioral symptoms: Surface hanging, flashing, clamping fins, isolating, reduced feeding, listing, erratic swimming? Each behavioral symptom has diagnostic weight.
External physical symptoms: White spots, gray film, lesions, ulcers, raised scales, fin erosion, exophthalmia, hemorrhage? Described in specific terms.
Gill observation: If accessible, what do the gills look like? Color, mucus, completeness?
Based on your inputs, KoiQuanta generates a differential diagnosis list ranked by probability given the symptoms entered. You're not required to follow it. Clinical judgment and local knowledge always matter. But you have a structured starting point rather than a best-guess.
Dose Calculators Integrated With Treatment Entry
When you select a treatment to initiate:
- You confirm your pond or tank volume (pre-filled from your stored profile)
- The dose calculator runs for the selected treatment at your current water temperature
- The calculated dose is presented with safety ranges and notes on temperature-dependent adjustments
- When you confirm the dose and administer, it logs automatically to the treatment record
This integration eliminates the step where most dosing errors occur: manually re-entering your pond volume into a separate calculator, or calculating from memory based on a formula you're not quite sure about.
For formalin, the dose adjusts downward at water temperatures above 22°C to account for the oxygen depletion risk. For potassium permanganate, the calculator accounts for water color and estimated organic load. For salt, it accounts for existing salt in the water and calculates the incremental addition to reach your target concentration.
Treatment Timeline and Follow-Up Scheduling
Every treatment entry includes:
- Date and time of treatment
- Dose administered
- Water parameters at time of treatment
- Scheduled re-treatment date (calculated from parasite life cycle and water temperature)
- Next assessment date
- Expected recovery milestone dates
The follow-up schedule shows up on your KoiQuanta dashboard so you don't have to remember to check back. The re-treatment alert appears on the correct day based on your logged water temperature, not just a fixed 7-day interval that ignores the fact that parasites develop twice as fast at 28°C as they do at 18°C.
Multi-Fish Tracking
Tracking multiple sick fish simultaneously in a disease outbreak is where paper-based systems fail. KoiQuanta lets you:
- Open individual treatment entries per fish
- Apply a shared treatment to the whole pond with a single entry
- Track which fish responded to treatment and which didn't
- Note individual mortality with timestamp (important for KHV/SVCV reporting)
When an outbreak affects the whole pond, the timeline for each fish starts from when their symptoms were first noted, not when the first fish showed signs. This distinction matters for understanding disease progression and for regulatory reporting.
Integration With Water Quality Log
Disease doesn't happen in isolation from water quality. The treatment tracker shows your water parameter history alongside the disease timeline, so you can see:
- What the water quality looked like in the 7 days before the outbreak
- Whether parameters deteriorated as the disease progressed
- How treatments affected water quality (formalin and KMnO4 both affect dissolved oxygen; salt affects fish osmoregulation)
- Whether recovery correlates with water quality improvement
This overlay, disease events on a water quality timeline, is the view that reveals the 70% of disease outbreaks that were preceded by undetected water quality deterioration.
Common Koi Diseases: What to Track for Each
Bacterial Infections (Aeromonas, Pseudomonas, Columnaris)
What to log:
- Location and size of all lesions (photograph with ruler for scale reference)
- Daily wound progression photos
- Temperature (affects antibiotic efficacy)
- Antibiotic type, dose, and delivery method (bath, injection, medicated food)
- Appetite and behavioral response
What the tracker tracks:
- Antibiotic treatment schedules
- Expected healing milestones
- Re-assessment reminders
- Alert if healing has stalled (indicating need for different antibiotic or secondary infection)
The bacterial infection treatment tracker covers this in full detail.
Parasitic Infections
What to log:
- Behavioral signs (flashing, surface hanging, gill observation)
- Treatment chemical and dose
- Water temperature at time of treatment
- Re-treatment schedule (life cycle dependent)
- Post-treatment scrape confirmation results
What the tracker tracks:
- Life-cycle-aware re-treatment scheduling
- Clearance confirmation reminders
- Alert if behavioral signs return after treatment (treatment failure or resistance)
Ulcers and Wound Care
What to log:
- Daily wound photographs
- Antiseptic treatments applied (topical)
- Antibiotic bath or injection records
- Wound measurement (width and depth) at each assessment
What the tracker tracks:
- Daily care reminders
- Healing milestone dates
- Insurance/vet documentation export
The ulcer treatment program provides the full protocol for wound care management.
KHV and Notifiable Diseases
What to log:
- Date of first clinical sign observation
- Affected fish list with individual symptoms
- Isolation actions taken with timestamps
- Veterinary contact and diagnosis date
- Regulatory authority notification date
This documentation sequence matters legally. The difference between "we noticed clinical signs and called the vet" (documented) and "we noticed clinical signs and called the vet" (undocumented) is the difference between demonstrable due diligence and unverifiable claims.
KoiQuanta's KHV-specific tracking is covered in the koi herpesvirus management guide with specific notation for OIE-aligned reporting structure.
What Makes KoiQuanta Different From a Health Log
KoiLogic is a basic health log with no differential diagnosis. You type notes, they're stored, but the software doesn't connect symptoms to treatment plans. KoiQuanta connects symptoms to treatment plans automatically, calculates dose, schedules follow-up, and tracks progress.
The practical difference shows up in a real-world scenario:
Saturday afternoon, you notice a fish hanging at the surface. In KoiLogic, you type "fish hanging at surface" and you're done. You've logged an observation. You still have to figure out what to do and remember when to check.
In KoiQuanta, you open a disease entry, answer the symptom prompts (behavioral: surface hanging; other signs: flared opercula, reduced appetite; water parameters: last test was Tuesday and showed ammonia 0, nitrite 0), get a differential showing gill parasites as the most likely cause given symptoms and time of year, select a treatment plan, get a calculated dose for your 3000-gallon pond at 22°C, log the treatment with a single confirmation, and receive a re-treatment reminder in 5 days. You've done more in 3 minutes than a health log does in 30.

FAQ
How do I log koi disease treatments?
Open a new disease entry in KoiQuanta and follow the symptom prompts. After recording symptoms, select the treatment plan from the suggested options or enter a custom treatment. The integrated calculator fills in the dose based on your pond volume (stored in your profile) and current water temperature. Confirm and administer. The treatment logs automatically with timestamp, dose, and water parameters. From that point, your follow-up schedule appears on the dashboard and re-treatment reminders appear automatically on the correct dates.
Can KoiQuanta track multiple sick fish at once?
Yes. You can open individual disease entries for each affected fish and manage them separately, which is useful for tracking which fish responded to treatment and which didn't. For a whole-pond outbreak, you can apply a shared treatment entry to all fish simultaneously and then note individual responses separately. The multi-fish view shows all active disease entries in a single dashboard, with status indicators for each, so you can see at a glance which fish are in active treatment, which are improving, and which require reassessment.
What diseases does KoiQuanta help treat?
KoiQuanta's treatment tracker includes built-in protocols for the most common koi diseases: bacterial infections (ulcers, fin rot, body rot), parasitic infections (Costia, Trichodina, gill and body flukes, ich, anchor worm, fish lice), fungal infections, KHV management (isolation and monitoring protocols), SVCV monitoring and reporting, dropsy management, and swim bladder disorders. The dose calculators cover the most common treatment chemicals: potassium permanganate, formalin, praziquantel, salt, and several antibiotic bath protocols. Custom treatment entries support any treatment not in the standard list.
