Aqion, working alongside Aqua Cura, provides fish health products for aquarium and pond disease treatment. With more than 20 years of experience, the brand serves both wholesalers and home fishkeepers, offering professional products and pricing through its dealer program. Aqion states that it is certified to ISO 9001:2015.

Its range includes treatments for parasites, fungal conditions and bacterial diseases. Prazi-Cura Powder is a praziquantel-based deworming treatment for koi and other fish, designed to address tapeworms and flukes. Prazi-Cura Liquid offers the same active ingredient in a liquid form for easier mixing. Kana-Cura is intended for various fish diseases, including dropsy, popeye, fin and tail rot, and septicemia; the company says it can be absorbed by fish when they are not eating and does not negatively affect filter beds during use.

Aqion sells through its online shop and provides shipping information, product guidance, and articles to support customers. Its offerings are focused on helping pond and aquarium owners care for fish health and manage common disease and parasite concerns.
