Aqua Meds KanaRx™

KanaRx™ Precautions

• Keep out of reach of children.
• Not for use on fish intended for human consumption.
• For ornamental fish use only.
• Use only as directed. Do not exceed the recommended dose.
• Increase aeration during treatment and monitor fish closely.
• Remove activated carbon and turn off UV sterilizers and ozone during treatment. Resume after treatment and a partial water change.
• Do not mix with other medications unless specifically advised by a qualified aquatic professional.
• Wear gloves and avoid contact with skin, eyes, and clothing. Wash hands after handling.
• Store tightly closed in a cool, dry place away from direct sunlight and moisture.
• Dispose of unused product and rinse water responsibly; do not release concentrated solutions directly into waterways.
• If irritation occurs, discontinue use and perform a partial water change.
• In case of accidental ingestion or eye contact, seek medical advice and show the product label.

Note: Water quality matters. Test ammonia, nitrite, pH, and temperature regularly during treatment. Poor water conditions can reduce effectiveness and stress fish.

KanaRx™ Directions for Use

Before You Begin

• Calculate true water volume (gallons or liters) as accurately as possible.
• Increase aeration. Remove activated carbon and turn off UV/ozone during treatment.
• Pre-dissolve powder in a container of pond/aquarium water and distribute evenly around high-flow areas.
• Monitor fish closely and test water (ammonia, nitrite, pH, temperature) throughout treatment.

Option 1 — Therapeutic Bath (Short, High-Intensity)

• Dose: 100 mg/L (≈ 0.38 g per gallon; 379 g per 1,000 gallons).
• Duration: 2 hours per day.
• Frequency: Daily for 7 days, or up to 7 days beyond symptom relief as needed.
• Notes: Provide strong aeration; return fish to the main system after each bath in clean, conditioned water.

Option 2 — Whole-Pond Immersion (Standard Course)

• Dose: 66 mg/L (≈ 0.25 g per gallon; 250 g per 1,000 gallons).
• Schedule: Dose once every 3 days for a total of 3 treatments.
• Water Changes: Perform a 50% water change between each treatment.

Option 3 — Medicated Food (Supportive/Follow-up)

• Mix Rate: 250–500 mg KanaRx™ per 100 g of food.
• Feeding Guide: Target ≈ 50 mg KanaRx™ per kg fish body weight daily for 5–7 days.
• Tips: Bind to food with a small amount of fish-safe oil or gelatin. Feed only what fish consume in a few minutes; remove uneaten food.

Quick Reference

During & After Treatment

• Maintain strong aeration throughout.
• Do not combine with other medications unless advised by a qualified aquatic professional.
• After the final dose, resume UV/ozone and reinstall carbon as desired; consider a partial water change to polish water.

Required Safety Statements

• Keep out of reach of children.
• Not for use on fish intended for human consumption.
• For ornamental fish use only.

Storage: Keep tightly closed in a cool, dry place away from moisture and direct sunlight.

KanaRx™ Medicated Food — Directions

Materials

• KanaRx™ powder
• Regular fish food (pellets or gel food)
• Binder: fish/krill oil (1–2% of food weight) or unflavored gelatin
• Measuring spoons/scale, bowl, spoon, gloves, zip bags/containers

Dosing Options

A) Simple Fixed-Rate Mix (most ponds): Use 250–500 mg KanaRx™ per 100 g food for 5–7 days. The lower end suits ~2% biomass/day feeding; the higher end suits ~1% biomass/day.

• 100 g food → 0.25–0.50 g KanaRx™
• 250 g food → 0.63–1.25 g KanaRx™
• 500 g food → 1.25–2.50 g KanaRx™

B) Precise Weight-Based Mix (advanced): Target ≈ 50 mg/kg fish BW/day for 5–7 days.
Daily dose (mg) = 50 × biomass (kg). Then: Food concentration (mg/g) = Daily dose ÷ daily food (g).

Method 1 — Oil-Bind

1. Weigh food (e.g., 200 g pellets) and measure KanaRx™.
2. Premix KanaRx™ with a little water; pour over pellets.
3. Add fish/krill oil at 1–2% of food weight (2–4 g per 200 g).
4. Mix thoroughly for even coating.
5. Air-dry 12–24 hours at room temperature (avoid heat >95°F).
6. Portion and store (see below).

Method 2 — Gelatin-Bind

1. Bloom 1–2 g gelatin per 100 g food in cool water; rest 5 minutes.
2. Warm gently to dissolve (do not boil).
3. Premix KanaRx™ with a little cool water; combine with lukewarm gelatin.
4. Fold in food to light tack; spread thin on a tray.
5. Set 1–2 hours, then air-dry up to 24 hours.
6. Cut/portion and store.

Feeding Schedule

• Feed medicated food for 5–7 consecutive days.
• Offer only what fish consume in a few minutes; remove uneaten food.
• Maintain strong aeration and monitor ammonia, nitrite, pH, and temperature.

Storage

• Use fresh when possible. Refrigerate portions up to 3–5 days.
• Freeze daily portions up to 3 months; thaw in the fridge before use.

Do / Don’t

• Do not combine with other medications in food unless advised by a qualified aquatic professional.
• Do avoid overfeeding; remove uneaten food promptly.

Required Safety Statements

• Keep out of reach of children.
• Not for use on fish intended for human consumption.
• For ornamental fish use only.

Q: How do NitroCure™, KoiCure™, and KanaRx™ differ?
A: All three are pure Aqua Meds antibiotic treatments, but each is best suited to different situations and treatment methods.

• NitroCure™ (nitrofurazone) – Primarily a waterborne treatment for external bacterial problems such as ulcers, fin rot, tail rot, mouth rot, and bacterial gill disease. NitroCure™ is especially useful when multiple fish are affected or when treating the pond, quarantine tank, or treatment system makes more sense than treating individual fish. It can be used as a preventative/new-fish quarantine treatment, therapeutic long-term bath, medium bath, or high-dose dip.
• KoiCure™ (oxolinic acid) – A versatile antibiotic that can be used as an immersion treatment or in medicated food. KoiCure™ is especially useful when bacterial infections are persistent, when redness or ulceration suggests a more established infection, or when the fish are still eating well and medicated food provides a practical way to treat systemically.
• KanaRx™ (kanamycin sulfate) – A strong broad-spectrum antibiotic used as an immersion or therapeutic bath treatment for serious bacterial infections. KanaRx™ can be a good option when another antibiotic has not produced the desired response or when the suspected bacteria may respond better to kanamycin.

Do not use NitroCure™, KoiCure™, and KanaRx™ at full strength at the same time. Using multiple antibiotics together does not automatically make treatment more effective and can add unnecessary stress to the fish and biological filtration.

When possible, choose the antibiotic and treatment method that best fit the symptoms, number of fish affected, severity of the problem, and whether the fish are still eating. If one treatment clearly works, there is usually no reason to change antibiotics simply for the sake of using something different.

Q: Which one should I use?
A: As a practical starting point:

• If several fish have primarily external bacterial problems and you want to treat the water, NitroCure™ is often a good first choice.
• If the fish are still eating well and you want to treat through medicated food, or if the infection is persistent or more established, KoiCure™ is often the better choice.
• If you are dealing with a serious bacterial infection or the fish have not responded as expected to another antibiotic, KanaRx™ may be the better treatment.

For significant ulcers or localized wounds, topical treatment can also be used along with the appropriate antibiotic treatment.
