Kent Marine Ammonia Detox 16 oz
Kent Marine Ammonia Detox 16 oz
Our Price: $7.48
In Stock

Kent Marine Ammonia Detox is the premier product for ammonia removal for tap or aquarium water. It is much stronger than competing products and is safer too. Some competing products contain toxic formaldehyde. Formaldehyde is more toxic than ammonia, and if too much is used, the results can be disastrous. Ammonia Detox is safe, even when overdosed. It neutralizes ammonia, chlorine and chloramine, instantly preparing tap water for immediate addition to the aquarium. Unlike some similar products, Ammonia Detox is even safe for sensitive hard and soft corals, anemones and other invertebrates, as well as freshwater and marine fish and plants. Use when preparing tap water for new aquariums, making water changes, or adding water to make up for evaporation. Ammonia Detox is safe to use directly in all freshwater and marine aquariums, including coral mini-reefs and also water gardens to neutralize toxic ammonia, as well. If the bacteria bed of an aquarium is accidentally killed by overuse of antibiotics, or other factors, Ammonia Detox will bind toxic ammonia, providing time to relocate the fish and invertebrates or to obtain other filtration media. In cases where too many fish are added too quickly, Ammonia Detox will bind ammonia until the existing bacteria multiply sufficiently to handle the ammonia. Ammonia Detox is also valuable for binding nitrites in fry rearing systems, where filtration cannot be used.

Our Price: $10.63

Kent Marine Pro Clear 16 oz (473 ml) clears cloudy water due to chemical reactions, disturbed detrius or other reasons. The special marine formula contains a long chain polymer that is attracted to the dirt particles and other organic materials which cause water cloudiness. This attraction creates debris clumps that are easy to filter out or that will settle to the aquarium bottom. Quickly clears water after performing water changes. Does not contain phosphates, nitrates, or silicates to cause undesirable algae or lime growth. For saltwater use only.

5 ml (1 tsp) treats 50 gallons of aquarium water.
