Kordon NovAqua Plus is the latest of technological developments in water conditioners for aquariums and ponds. NovAqua Plus dechlorinates water, removes toxic heavy metals including copper; and adds electrolytes and a protective slime coat - vitamins and echinacea. Tap water may be safe for humans, but in almost all localities it is not safe for fishes and aquatic invertebrates. Tap water needs to be modified by using NovAqua Plus when setting up aquariums or making water changes, and when preparing salt water for marine aquariums. NovAqua Plus provides, in a single product, everything necessary to handle all of the needs when treating tap water for aquatic life. NovAqua Plus is recommended to be used with AmQuel Plus, with which it is fully compatible. 1 oz bottle treats 60 gallons.
