Dosage Chart:

Calculate dose based on accurate pond volume.

Application Instructions:

1. Calculate pond volume accurately (length × width × average depth × 7.48 for gallons)
2. Ensure strong aeration is running (critical—see below)
3. Measure appropriate dose (1 fl oz per 300 gallons)
4. Dilute in bucket of pond water before adding
5. Distribute evenly throughout pond
6. Water will turn purple—this is normal and expected
7. Monitor purple color for 2-4 hours
8. If color fades quickly (under 2 hours), add additional 0.5 fl oz per 300 gallons
9. Maintain aeration throughout treatment period

Understanding the Purple Color:

The purple/pink color indicates active potassium permanganate in the water. The color should persist for 2-4 hours as the treatment works. If the color fades quickly (under 2 hours), it means your pond has high organic load—the permanganate is being consumed rapidly by organic matter. Add an additional half-dose to maintain treatment strength. The color will gradually fade to brown/tan as the permanganate is consumed, then disappear completely.

Treatment Protocols:

For Active Parasite Infections:

1. Apply initial dose (1 fl oz per 300 gallons)
2. Maintain purple color for 2-4 hours
3. Wait 3 days
4. Repeat treatment (second application)
5. Wait 3 days
6. Apply third treatment if needed
7. Monitor fish for improvement

For Monthly Maintenance:

• Apply once per month at standard dose
• Helps control organic buildup
• Reduces parasite pressure before problems develop
• Maintains water clarity
• Especially beneficial in heavily stocked ponds

For Water Quality Improvement:

• Apply when water becomes murky or brown
• Breaks down dissolved organics causing discoloration
• Oxidizes organic debris and sludge
• Improves clarity within 24-48 hours
• May need to repeat if organic load is very high

Critical: Aeration Required

⚠️ Maintain strong aeration during all Purple Magic treatments. Potassium permanganate consumes oxygen as it oxidizes organic matter, especially in warm water. Without adequate aeration, fish can experience oxygen stress. Use air stones, air pumps, or waterfalls to ensure high oxygen levels throughout treatment. This is mandatory, not optional.

Emergency Neutralization:

If fish show signs of stress during treatment (gasping, lethargy, loss of balance):

1. Immediately add 3% hydrogen peroxide at 100 mL per 1,000 gallons
2. This neutralizes potassium permanganate instantly
3. Increase aeration dramatically
4. Perform partial water change if needed
5. Monitor fish closely for recovery

Have hydrogen peroxide on hand before treating—it's your emergency antidote.

Expected Results:

Frequently Asked Questions

Q: What is potassium permanganate, and how does Purple Magic work?
A: Potassium permanganate is a powerful oxidizing agent that works in two ways: it kills external parasites by disrupting their cellular function, and it breaks down organic matter (dissolved organics, debris, sludge) that clouds water and stresses fish. When you add Purple Magic to your pond, it turns the water purple/pink—this color indicates active permanganate working in the water. As it oxidizes parasites and organic matter, the color gradually fades to brown/tan, then disappears. The dual-action makes it unique—you're treating parasites AND improving water quality simultaneously, addressing both the symptoms and underlying environmental stress that weakens fish.

Q: How long should the purple color last, and what does it mean if it fades quickly?
A: The purple color should persist for 2-4 hours in a healthy pond with moderate organic load. If the color fades in under 2 hours, it means your pond has high organic load—the permanganate is being consumed rapidly by organic matter, leaving less available to treat parasites. In this case, add an additional half-dose (0.5 fl oz per 300 gallons) to maintain treatment strength. Very murky or heavily stocked ponds may need multiple additional doses to maintain color. If color fades in under 30 minutes, your pond has extremely high organic load and needs aggressive water quality improvement—consider large water changes, filter cleaning, and reducing feeding before retreating.

Q: Why is strong aeration so critical during Purple Magic treatment?
A: Potassium permanganate consumes oxygen as it oxidizes organic matter—this is how it works. In warm water (above 70°F) or ponds with high organic load, oxygen consumption can be significant. Without strong aeration to replace consumed oxygen, fish can experience oxygen stress (gasping, lethargy, loss of equilibrium). This is especially dangerous at night when plants aren't producing oxygen. Always run air stones, air pumps, or waterfalls at maximum during treatment. If you see fish gasping at the surface during treatment, it's an oxygen emergency—neutralize immediately with hydrogen peroxide, increase aeration, and perform a water change.

Q: How do I use hydrogen peroxide to neutralize Purple Magic in an emergency?
A: If fish show stress during treatment (gasping, lethargy, loss of balance), immediately add 3% hydrogen peroxide at 100 mL per 1,000 gallons. The hydrogen peroxide reacts with potassium permanganate and neutralizes it instantly—you'll see the purple color disappear and turn brown. This stops the treatment and oxygen consumption immediately. After neutralizing, increase aeration dramatically and monitor fish closely. Perform a 25-50% water change if fish don't improve quickly. This is why you should always have hydrogen peroxide on hand before treating—it's your emergency antidote. Don't wait to buy it if fish are in distress.

Q: Can I use Purple Magic for monthly maintenance, or is it only for treating active problems?
A: Purple Magic is excellent for both active treatment and monthly maintenance. For active parasite infections, treat every 3 days for up to 3 applications. For monthly maintenance, apply once per month at standard dose (1 fl oz per 300 gallons). Monthly maintenance helps control organic buildup, reduces parasite pressure before problems develop, maintains water clarity, and supports overall pond health. This is especially beneficial in heavily stocked ponds where organic load accumulates quickly. Many experienced koi keepers use Purple Magic monthly as preventive care, then increase frequency if problems appear. Think of it like changing your car's oil—regular maintenance prevents bigger problems.

Q: Will Purple Magic harm my biofilter or beneficial bacteria?
A: When used at recommended doses, Purple Magic does not significantly harm beneficial bacteria in established biofilters. Potassium permanganate is a strong oxidizer, but at treatment concentrations (1 fl oz per 300 gallons), the impact on biofilters is minimal. Your beneficial bacteria should continue functioning normally during and after treatment. However, if you drastically overdose or treat very frequently, you may see some biofilter impact. Monitor ammonia and nitrite levels after treatment—if they spike, your biofilter was affected and you should reduce feeding and do water changes until it recovers. Most ponds experience no biofilter issues with proper dosing.

Q: Can I combine Purple Magic with other treatments like salt or medications?
A: No, do not combine Purple Magic with other medications or treatments. Potassium permanganate is a strong oxidizer that can react unpredictably with other chemicals, potentially creating toxic compounds or neutralizing both treatments. Use Purple Magic alone during its treatment cycle. If you need to use other medications, complete the Purple Magic treatment cycle first (wait until color has completely faded), perform a 25-50% water change, wait 24-48 hours, then proceed with other treatments. The exception is the emergency use of hydrogen peroxide to neutralize Purple Magic—that's the only chemical you should add during active treatment.

Q: How many treatments are needed to eliminate parasites completely?
A: Most parasite infestations resolve with 2-3 treatments spaced 3 days apart. The first treatment kills adult parasites and reduces organic load. The second treatment (3 days later) catches any parasites that survived or newly hatched from eggs. A third treatment (another 3 days later) ensures complete elimination. If parasites persist after 3 treatments, reassess your diagnosis—you may be dealing with a different parasite type (like anchor worm or fish lice, which Purple Magic doesn't treat), or you may have underlying water quality issues allowing reinfection. Also verify you're dosing correctly and maintaining the purple color for adequate time. Most cases resolve within 2 treatments if dosed properly.

Q: Is Purple Magic safe for all fish species, and what about plants?
A: Purple Magic is safe for koi, goldfish, and most ornamental pond fish when used at recommended doses with proper aeration. Some very sensitive species or scaleless fish may require closer monitoring—watch for stress signs and be prepared to neutralize if needed. As for plants, potassium permanganate can damage or kill delicate aquatic plants, especially submerged plants and floating plants. Hardy plants like water lilies and lotus usually tolerate treatment, but may show minor leaf damage. If you have expensive or rare plants, consider removing them during treatment. Marginal plants (growing in shallow water or bog areas) are generally unaffected. The oxidizing action that kills parasites can also damage plant tissues, so there's always some trade-off.
