Nitrate Sponge is a granular zeolitic medium which works by two methods: 1) It slowly, but directly adsorbs small amounts of ammonia that are released by fish and natural processes, and 2) it fosters anaerobic bacterial denitrification due to its physical porous structure. This denitrification slowly reduces nitrate levels in the aquarium. It works well in freshwater tanks or tap water to remove toxic ammonia directly! Nitrate Sponge prolongs the time allowed between water changes by keeping nitrates low. 2 qt. jar treats a 50 gallon tank.

Absorbs phosphate and silicate from saltwater and freshwater aquariums. 2 qts. treats 200 gallons.

Removes organic pollutants and stains from saltwater and freshwater aquariums. 1 qt. treats 400 gallons.

Pro-Tech Coat (Marine)
Pro Tech Coat Marine neutralizes chlorine and heavy metals and restores the natural slime coat of fish, which relieves stress and calms and protects against abrasions. It helps acclimatize fish to new surroundings, and it can be used when preparing tap water, making water changes, adding new fish, handling fish, transporting fish, or when fish are wounded. Pro Tech Coat Marine contains polyvinylpyrrolidone as the coating ingredient, unlike some others that contain cheap fillers such as aloe vera and carboxymethylcellulose, which then decay in the aquarium and lower the redox and the overall water quality. Pro Tech Coat Marine does not affect biological filtration and is safe for all marine species including sensitive hard and soft corals and other invertebrates.

Pro-Tech Coat (Freshwater)
Kent Pro Tech Coat Freshwater neutralizes chlorine and heavy metals in freshwater aquariums. It restores the natural slime coating to relieve fish stress and to calm and protect against abrasions. It helps acclimatize fish to new surroundings and can be used when preparing tap water, making water changes, adding new fish, handling fish, transporting fish, or when fish are wounded.

Replaces biologically important trace minerals which are used by fish and invertebrates and removed through filtration. 16 oz. treats 4,700 gallons.

Kent Pro Clear produces and maintains crystal clear aquarium water without affecting pH. It also works, unlike some products, without clogging fish's gills, suffocating them, or causing invertebrates to close up. Kent Pro Clear is completely safe for all marine fish and invertebrates. It uses a blend of high tech polymers that safely flocculate any algae, dirt, bacteria, or other cloudy-water causing particles. Contains no phosphates, nitrates, or silicates to cause undesirable algae or slime growth. Not an algaecide and 100% biodegradable. 16 oz. treats 4,700 gallons. Formulas for both fresh and saltwater aquariums.

This specially formulated carbonate hardness (KH) builder is designed to adjust the pH in saltwater aquariums to the optimum range of 8.0 - 8.3 while building the KH. Mixes clear with little or no cloudiness or precipitation. 500 grams treats 2,800 gallons.

This specially formulated pH is designed to adjust the pH in saltwater aquariums to the optimum range of 8.0 - 8.3 while building the KH. Mixes clear with little or no cloudiness or precipitation. Marine Aquarium pH Buffer is similar to Superbuffer-dKH, but designed specifically for fish-only tanks. 500 grams treats 2,800 gallons.

Organic oxidizer that cleans and conditions. Promotes a pristine aquarium. 16 oz. treats 9,400 gallons.

Neutralizes ammonia, chlorine, and chloramines and instantly "ages" tap water, allowing immediate addition of water to aquariums. Much stronger than competing products, and safer it does not contain toxic formaldehyde, which is more toxic than ammonia and used in some conditioners. Safe for fresh and saltwater. 16 oz. treats 1,920 gallons.

Enhanced Pro-Buffer dKH with coralline accelerator raises alkalinity or buffering capacity and works automatically to control pH in any marine aquarium. 16 oz. of the solution treats 1,900 gallons of water.

Vitamin C has been shown to enhance the immune system of fishes and invertebrates, as well as facilitate the metabolism of fatty acids, and stimulate the production of connective tissue. Can be used as a daily supplement or when treating damaged/sick fish. 4 oz. treats 5,900 gallons.
