Target the problem.Protect the pond.
Aqua Meds makes purpose-built treatments for koi and goldfish keepers — parasite and bacterial medications, water conditioners, and beneficial bacteria that each target a specific problem instead of a one-size-fits-all fix. Diagnose, dose, and get your fish back to health.

Built by koi people, for koi people
Aqua Meds was founded by Mark Bodycott on a simple frustration: too many pond products are vague, watered-down, and sold on marketing instead of results. Aqua Meds does the opposite — concentrated, single-purpose formulas that name the parasite, the bacteria, or the water problem they're built to solve.
That's exactly why we stock the line at Mystic Koi. When a customer walks in with a fish covered in flukes, an ulcer that won't close, or a pond that crashes its pH every night, we want a treatment we can point to with confidence — and a dosage we can explain in one sentence.
Targeted formulas
Each product solves one problem — no guesswork, no kitchen-sink blends.
Filter-friendly
Formulated not to wipe out the beneficial bacteria in your biofilter.
Honest dosing
Every product ships with a clear per-gallon dosage chart — no mystery.
Fish-first
Concentrated, well-tolerated actives designed with koi safety in mind.
Treat water first, fish second
Before reaching for a medication, test your water. Ammonia, nitrite, low KH and pH swings cause most "disease" symptoms in koi. Never mix Aqua Meds products with untreated tap water, don't combine medications, and follow the dosage chart on each product page exactly.
Not sure how much your pond holds?
Accurate dosing starts with accurate volume. Use our pond calculators to get your gallons, then match it to any Aqua Meds dosage chart — or read the Koi Health Guides for step-by-step treatment plans.
