Seachem Prime 500ml

Prime® is the complete and concentrated conditioner for both fresh and salt water. Prime® removes chlorine, chloramine and ammonia. Prime® converts ammonia into a safe, non-toxic form that is readily removed by the tanks biofilter. Prime® may be used during tank cycling to alleviate ammonia/nitrite toxicity. Prime® detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Prime® also promotes the production and regeneration of the natural slime coat. Prime® is non-acidic and will not impact pH. Prime® will not overactivate skimmers. Use at start-up and whenever adding or replacing water. Nearly all companies manufacture a product that removes chlorine. None of those, however, can compare in quality, concentration, or effectiveness to Seachems flagship product: Prime®. Prime® is the second most concentrated dechlorinator on the market after our own aquavitro alpha™. A single 100 mL bottle will treat 1000 US gallons of tap water. Prime® will remove both chlorine and chloramines from municipal water supplies. Prime® also contains a binder which renders ammonia, nitrite, and nitrate non-toxic. It is very important to understand how those two functions work together. All dechlorinators operate through a chemical process known as reduction. In this process, toxic dissolved chlorine gas (Cl2) is converted into non-toxic chloride ions (Cl-). The reduction process also breaks the bonds between chlorine and nitrogen atoms in the chloramine molecule (NH2Cl), freeing the chlorine atoms and replacing them with hydrogen (H) to create ammonia (NH3). Typically, dechlorinators stop there, leaving an aquarium full of toxic ammonia! Seachem takes the necessary next step by including an ammonia binder to detoxify the ammonia produced in the reduction process.

Neutral Regulator, 500 g / 1.1 lbs

It softens water by precipitating calcium and magnesium while removing any chlorine, chloramine, or ammonia. The use of Neutral Regulator? makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulator? with Acid Regulator? (or Discus Buffer?). To raise pH above 7.0 use with Alkaline Regulator?. All of these products will enhance and stabilize the freshwater aquarium environment. Use Fresh Trace? to restore the proper level of trace elements required by thriving, healthy freshwater community fish.DIRECTIONS: Use 1 level teaspoon for every 40?80 L (10?20 gallons*) once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator? may be added directly to the aquarium at any time. Ideally, it should be used when adding or changing water by dissolving in the replacement water.i500 g / 1.1 lbs (Treats 8000 L (2115 US Gallons))

API Stress Zyme, 64-Ounce

Stress Zyme is a biological filter additive containing live bacteria that improves the development of the biological filter and helps clean a dirty aquarium. The build-up of organic pollution in the aquarium inhibits the growth of nitrifying bacteria. The bacteria in Stress Zyme keep conditions in the aquarium right for the development of the biological filter by consuming harmful organic pollutants. This speeds the development of the biological filter in newly set up aquariums. A build-up of organic compounds also promotes the growth of disease-causing organisms in the aquarium. Stress Zyme keeps the biological filter working properly by keeping the aquarium gravel and filter clean. Water quality and living conditions are improved when Stress Zyme is used on a regular basis. Each teaspoonful of Stress Zyme contains 300 million bacteria. These bacteria are in a dormant state and become active when added to the aquarium. Stress Zyme has a five-year shelf life and does not require refrigeration. Stress Zyme is effective in freshwater and marine aquariums.
