API Liquid Super ICK Cure — Freshwater & Saltwater Fish Medication, 16 oz

Overview

API Liquid Super ICK Cure is a ready-to-use liquid medication designed for home aquariums. It targets ich parasites in both freshwater and saltwater fish and helps support a protective slime coat during an outbreak. While results can vary based on tank conditions and timing, many hobbyists use it to manage white spot disease in a routine care plan. With almost 60 years of API experience, this solution sits alongside testing kits, water conditioners, and quality foods to help you maintain a healthy underwater world.

What it treats and how it helps

The product is formulated to address ich (Ichthyophthirius) in fish and may support the fish’s natural defenses as the parasite is addressed. It can also help mitigate secondary bacterial infections that sometimes follow stress from an Ich outbreak. This approach aligns with API’s broader goal of providing reliable aquarium care solutions for tropical community fish, cichlids, goldfish, and more.

Usage guidance at a glance

• Applicable in freshwater or saltwater aquariums; not recommended for reef tanks with invertebrates.
• Administer the first dose at the first sign of white spots, then repeat after 48 hours as directed.
• Scaleless fish may require half the normal dose to reduce sensitivity.
• Water may take on a slight color during treatment; this is temporary and can be removed with activated carbon.
• Follow label directions precisely for tank size and fish type to guide dosing amounts.

How it works in your tank

The medicine acts quickly to address the ich parasite and supports a healthier mucus layer on fish skin and gills, helping reduce stress during recovery. It is not a substitute for proper aquarium hygiene, quarantine practices, or ongoing monitoring of water quality. The suspension is designed for easy dosing and can be integrated into a regular care routine alongside API’s testing and conditioning products.

Practical tips for success

To maximize comfort and clarity in your aquarium, consider the following tips:

• Test water parameters before and after treatment to maintain stable conditions.
• Use activated carbon after treatment to remove any residual color from the water.
• Avoid combining with other medications unless directed by product guidelines.
• Observe fish closely for lingering spots or unusual gilling, and adjust care as needed.

Important notes

• Reef aquariums or tanks with sensitive invertebrates may be affected; exercise caution.
• Not suitable for reef environments with corals or certain invertebrates.
• Always dose according to the product label and consult a professional if signs persist.
