KoiLogic handles the basics well. KoiQuanta adds seven specific features that KoiLogic simply doesn't offer: the dose calculators, quarantine automation, compliance tools, and audit export make up most of that $10/mo difference.
KoiLogic: What It Does Well
KoiLogic built its reputation on a clean, easy-to-use health log. The interface is intuitive. Setup takes minutes. For hobbyists who want a digital record of water tests and fish observations, it does the job without friction.
The $29/mo price point is genuinely accessible. If you have one pond, a handful of fish, and you're not buying new stock frequently, KoiLogic may be all you need.
It's a health log. It records what you tell it.
Where KoiLogic Falls Short
The core limitation is that KoiLogic is passive. It logs what you enter; it doesn't calculate, automate, or flag.
No dose calculator means every treatment calculation is manual. You're using online tools or pen and paper to figure out how much formalin to add, then manually checking whether that dose is safe. The gap between "I calculated X" and "X is actually in the safe range for my water temperature" is where mistakes happen.
No quarantine automation means every quarantine step is a manual reminder system. You set your own calendar alerts. You track your own retreatment schedule. There's no workflow guiding you from intake to clearance.
For dealers, the missing compliance tools are the biggest problem. KoiLogic generates no audit-ready records and has no USDA-compatible export. If a USDA inspector shows up, your KoiLogic data is not what they need to see.
KoiQuanta: What It Adds
Automated Dose Calculators
KoiQuanta calculates treatment doses from your pond volume, stock solution concentration, and target therapeutic level. Every result is checked against the safe range for that compound at your current water temperature. You get a dose and a confirmation that it's appropriate, not just a number.
Quarantine Automation
The quarantine workflow in KoiQuanta takes you from new fish arrival through the full 30-day protocol. It schedules retreatment prompts, flags observation windows, and generates clearance records when all criteria are met. You're not managing this manually.
Dealer Compliance Tools
For dealers, KoiQuanta generates audit-ready records as a side effect of normal use. Every treatment, every quarantine step, every water test is timestamped and organised. When you need a USDA-compatible export, it takes seconds.
Mobile Access
KoiLogic is desktop-focused. KoiQuanta works on any device: you can log a treatment pond-side on your phone and review the full record on your desktop later.
Does KoiLogic Have Quarantine Automation?
No. KoiLogic does not offer quarantine automation. You can log quarantine events manually, but there's no automated workflow that schedules retreatments, prompts observations at the right intervals, or generates clearance documentation. This is one of the most commonly cited reasons hobbyists switch from KoiLogic to KoiQuanta.
Who Should Use KoiLogic
KoiLogic makes sense if:
- You have one established pond with no new fish introductions
- You never treat with chemicals (or treat very rarely)
- Budget is genuinely the deciding factor and $10/mo matters
- You want a simple, low-friction record for your own reference
Who Should Use KoiQuanta
KoiQuanta makes sense if:
- You buy new fish regularly and take quarantine seriously
- You treat with salt, formalin, KMnO4, prazi, or other chemicals
- You're a dealer or importer with compliance obligations
- You want dose calculations checked against safe ranges automatically
- You manage multiple ponds
Does KoiLogic have quarantine automation?
No. KoiLogic offers health logging but does not include an automated quarantine workflow. You can manually record quarantine events, but there are no scheduled prompts, retreatment reminders, or clearance documentation features. If quarantine automation is a priority, and it should be for anyone regularly introducing new fish, KoiQuanta is the platform that offers it.
Is KoiQuanta worth the extra $10/mo over KoiLogic?
For hobbyists who buy fish regularly, treat with chemicals, or manage more than one pond, yes. The dose calculators alone save time on every single treatment, and the safe-range flagging prevents potentially fatal errors. For dealers, the compliance tools make it a practical necessity. For a casual hobbyist with a stable, established pond and no new introductions, the price difference may not be justified.
Which software is better for koi dealers?
KoiQuanta, clearly. KoiLogic has no dealer-specific features: no audit-ready records, no USDA-compatible export, no compliance workflow. KoiQuanta was built with dealers in mind from the start, and generates compliant documentation as part of normal daily use. For any dealer facing USDA or state import inspections, KoiLogic simply isn't equipped for the job.

KoiQuanta and KoiLogic are two competing koi pond management software platforms designed to help hobbyists and dealers track fish health, water quality, and treatment records. This comparison breaks down their key differences so you can decide which fits your needs. KoiQuanta costs $39/mo and includes quarantine automation, dose calculators, and dealer compliance tools. KoiLogic costs $29/mo and covers the basics with a solid health log. The right choice depends on how actively you manage fish health and whether you handle imports or treatments regularly.
How much does KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You? cost?
KoiLogic is priced at $29/mo, making it the more budget-friendly option. KoiQuanta costs $39/mo — a $10/mo difference that adds up to $120/year. That gap buys you automation features KoiLogic doesn't offer: built-in dose calculators, quarantine workflow automation, compliance tools, and audit-ready export. If you're a casual keeper tracking basic water parameters, KoiLogic's price point is genuinely accessible. If you're treating fish regularly or managing dealer compliance, the extra $10/mo likely pays for itself in time saved.
How does KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You? work?
Both platforms let you log water quality readings, track fish health events, and maintain treatment records over time. KoiQuanta goes further by automating quarantine workflows — prompting you through each stage and flagging missed steps. Its dose calculators compute treatment amounts based on pond volume and fish weight, eliminating manual math. KoiLogic requires you to calculate doses yourself and manage quarantine manually. KoiQuanta also generates compliance-ready audit exports, useful for dealers managing import documentation. Both platforms are cloud-based and accessible from desktop or mobile.
What are the benefits of KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You??
KoiQuanta's primary benefit is automation. Users avoid the manual dose calculations that KoiLogic requires, with reports of KoiLogic users spending 3x longer on treatment math. Quarantine automation reduces the risk of skipped steps that can compromise fish health. For dealers, compliance tools and audit exports simplify documentation that would otherwise be done manually. KoiLogic's main benefit is simplicity and lower cost — it covers core health logging without the complexity of advanced features, which suits hobbyists who treat fish infrequently and don't need dealer-grade compliance tools.
Who needs KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You??
KoiLogic suits casual hobbyists who maintain a backyard pond, log water parameters occasionally, and treat fish a few times a year. KoiQuanta is built for serious keepers, collectors with high-value fish, and koi dealers who need quarantine compliance, frequent treatment calculations, and documentation trails. If you're importing fish, selling koi, or managing a large collection where a health mistake is costly, KoiQuanta's tools are designed for your risk profile. The more seriously you treat fish health management, the more KoiQuanta's automation justifies its price.
How long does KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You? take?
Setup for both platforms is straightforward and typically takes under an hour to enter your pond details, baseline water parameters, and initial fish inventory. Day-to-day logging takes a few minutes per session. Where KoiQuanta saves time is in treatment workflows — dose calculators run instantly versus manual calculation that can take 15–30 minutes per treatment event. Over a month of active fish management, KoiLogic users report spending roughly 3x more time on calculations alone. Time investment scales with how actively you're treating fish or managing quarantine.
What should I look for when choosing KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You??
Focus on five things: dose calculation support (manual vs. automated), quarantine workflow management, compliance and audit export capabilities, price relative to your usage frequency, and ease of daily logging. If you treat fish rarely, a health log and water quality tracker may be all you need — KoiLogic covers that. If you calculate treatment doses regularly, manage quarantine protocols, or need documentation for dealer compliance, look specifically for automation and export features. Also consider whether the platform works on your preferred device and integrates with how you already track your fish.
Is KoiQuanta vs KoiLogic: Which Koi Management Software Is Right for You? worth it?
For serious koi keepers and dealers, KoiQuanta is worth the $39/mo. The dose calculators alone eliminate a significant source of error and wasted time, and quarantine automation reduces the risk of costly health mistakes with high-value fish. The $10 premium over KoiLogic is justified if you're treating fish regularly or managing import compliance. For casual hobbyists who log water quality a few times a month and rarely treat fish, KoiLogic's $29/mo is a reasonable, capable option. Match the tool to the intensity of your fish health management.
