Dechlor to save your fish from the Killer Chlorine & Chloramine

When adding water to a pond, the tap water that comes from your hose contains chlorine and chloramines (see blog “what is chloramine”) which are harmful to your fish. Chlorine is toxic to most aquatic life, and it can cause stress and bad burns to the fish once it reaches the gills and its internals. Chlorine will cause burns upon contact, damaging the gills, scales, and breathing tissue of goldfish and koi. Also, interestingly, it readily enters the blood stream after it passes through the gills, causing internal burning, stress, and significant pain to the fish. The solution to this is to add the Pond Company’s Dechlor. Dechlor is short for a water dechlorinator, which is a water conditioner that neutralizes the chlorine, chloramine, and other heavy harmful substances. Dechlor should always be used whenever we add water to a pond, and whenever we do a water change to neutralize the chemicals before they affect the fish and the ecosystem. A bottle of the Pond Company’s Dechlor can be purchased for only $17.95 (see store), please give us a call if you are interested in purchasing (626)-284-5937 or drop us an email at:

Chlorine & Chloramine Kill!

What is Chloramine [ klôr′ə-mēn′ ]?

It is a way to bond chlorine to water. We remember when Chloramines first started to be used in the 1980’s. It is added by our metropolitan water districts in combination with chlorine to “sanitize” and disinfect the tap water that comes to your home and business. “Sanitize” means “kills everything” living without discretion, thus this means your fish too! Prior to that time Chlorine would rapidly dissipate from the water, but the Chloramines make it stay in the water for a longer period of time. Chloramines are a group of chemical compounds that contain Chlorine and Ammonia. Chloramine locks the Chlorine and Ammonia to the water molecule, so it stays active in the water for a longer period of time. Although we are told that the use of Chloramine in our water makes it “safer” for humans to drink (debatable given all the bottled water we buy), it is definitely harmful to fish. Chloramines are toxic to fish, because the fish will take up chloramines directly through their burned gills into their blood stream – not good! We recommend the water used for your pond should always be free from Chloramines. (See blog on how to treat for Chlorine & Chloramine)
