Ich doesn't wait, and neither should your treatment. Fritz FixIck gets to work fast without the harsh chemicals found in most parasite medications.

Unlike traditional ich treatments that rely on formaldehyde or malachite green, FixIck uses Gentian Violet, a gentler active ingredient that's effective against a range of external protozoan parasites while being easier on your fish and biological filter.

Why hobbyists reach for FixIck:

• No formaldehyde or malachite green — gentler on sensitive fish and scaleless species
• Broad-spectrum coverage — treats ich (Ichthyophthirius), Chilodonella, Trichodina, and Tetrahymena
• Works in freshwater and saltwater — one bottle covers both setups
• 16 oz treats up to 946 gallons — solid value for larger tanks or repeat treatments
• May tint water slightly purple — remove ornaments beforehand if needed; clears after treatment

For best results, raise tank temperature to 82–85°F before dosing to accelerate the parasite life cycle and maximize medication exposure. Remove all chemical filtration before starting and only resume after the full course is complete.

Dosage & Treatment Schedule:

• Day 1: 5 ml (1 tsp) per 10 gallons
• Day 2: 5 ml (1 tsp) per 10 gallons
• Day 3: 25–30% water change
• Day 4: 5 ml (1 tsp) per 10 gallons
• Day 5: 5 ml (1 tsp) per 10 gallons
• Day 6: 25–30% water change (resume chemical filtration)

If needed, repeat the full 6-day course without chemical filtration.
