Purple Magic – Koi Pond Purifier & Parasite Control
Purple Magic is a concentrated liquid potassium permanganate treatment formulated for koi and ornamental ponds. It provides powerful oxidation to control external parasites while breaking down organic debris that clouds water and stresses fish. Purple Magic supports clearer water, reduced parasite pressure, and overall improved pond health.
What Purple Magic Treats
External Parasites
- Trichodina
- Costia
- Chilodonella
- External flukes
Water Quality Issues
- Excess dissolved organics
- Murky or brown water
- Organic debris and sludge
- High bacterial load from decaying waste
Purple Magic acts as both a parasite control agent and a strong oxidizer that improves clarity and reduces the environmental stress that weakens fish.
Why Choose Purple Magic
Dual-Action Performance
Targets parasites while simultaneously reducing organic load.
Accurate Liquid Dosing
1 oz per 300 gallons ensures consistent treatment strength.
Improves Water Quality
Breaks down debris and dissolved organics for cleaner, clearer water.
Safe for Biofilters
Does not damage beneficial bacteria when used correctly.
Ideal for Both Treatment and Monthly Maintenance
Supports a healthier pond long-term, especially in heavily stocked systems.
How to Use Purple Magic
Standard Pond Treatment
Dose 1 fl oz per 300 gallons. Maintain the purple tint in the water for up to 4 hours.
If the Color Fades Quickly
If the purple color disappears in under 2 hours, add 0.5 fl oz per 300 gallons.
Treatment Frequency for Parasites
For active parasite issues, treat every three days for up to three applications.
Monthly Maintenance
Purple Magic may be applied once per month to help control organic load, reduce parasite pressure, and maintain water clarity.
Aeration Requirements
Maintain strong aeration at all times during treatment. Potassium permanganate consumes oxygen, especially in warm water.
Neutralizing
If fish show stress, neutralize with 3% hydrogen peroxide at 100 mL per 1000 gallons.
Frequently Asked Questions
What does Purple Magic treat?
Purple Magic controls external parasites including trichodina, costia, chilodonella, and external flukes. As a strong oxidizer, it also improves water quality by breaking down excess dissolved organics, murky or brown water, organic sludge, and the high bacterial load created by decaying waste.
How do I dose Purple Magic?
The standard pond dose is 1 fl oz per 300 gallons. Maintain the purple tint in the water for up to 4 hours. If the color fades in under 2 hours, add another 0.5 fl oz per 300 gallons. Always follow the full instructions on this page.
How often should I use Purple Magic?
For an active parasite problem, treat every three days for up to three applications. For ongoing upkeep, it can be applied once per month to control organic load, reduce parasite pressure, and keep water clear.
Is Purple Magic safe for my biofilter?
Yes. When used correctly at the recommended dose, Purple Magic does not damage the beneficial bacteria in your biofilter.
Do I need aeration while treating?
Yes. Maintain strong aeration at all times during treatment, because potassium permanganate consumes oxygen, especially in warm water. If fish show signs of stress, you can neutralize with 3% hydrogen peroxide at 100 mL per 1,000 gallons.
