PondPrep - Concentrated Dechlorinator & Tap Water Conditioner

City water is full of chlorine, chloramine, ammonia and heavy metals and if you add fish and plants to your pond without removing those materials you could be putting them in danger. SuperNatural PondPrep is formulated quickly remove chlorine, chloramine, ammonia and heavy metals when starting up a pond, when replacing water due to evaporation or after a partial water change. PondPrep is professional strength, the most concentrated formula in the market, so you only need to apply 1 oz. for every 1000 gallons of pond water.

Here is a quote taken from the CDC (Center For Disease Control and Prevention) website:

Will Chloramine Affect My Pets or Plants?

Chlorine and chloramine are toxic to fish, other aquatic animals, reptiles and amphibians. Unlike humans and other household pets, these types of animals absorb water directly into the blood stream. Don’t keep these animals in water that contains these disinfectants. Unlike chlorine, chloramine cannot be removed by letting water sit out for a few days. However, products are available at aquarium supply stores that can remove chloramine. Ask your local pet store about methods of removing disinfectants from water for these pets.

Even if you are on well water, using PondPrep regularly may also be beneficial as well water can also have elevated levels of ammonia and heavy metals that can be harmful to fish and other aquatic life.

  • Makes Tap Water Safe For Fish and Plants
