What Is Chlorine?
You probably know that we humans use chlorine in pools and in drinking water to a certain degree. When you go swimming, it’s that stuff that burns your eyes and makes them all red and itchy after you are done swimming. Chlorine is a naturally occurring element that humans often use as a water disinfectant. In small doses it does a great job at killing off various bacteria, viruses, and parasites in the water.
Generally speaking, in smaller doses, chlorine is not harmful to humans, but of course you can’t swallow huge amounts of pure chlorine without paying the price. That being said, chlorine is very toxic to fish, so it’s not something that you want to have in your aquarium. It will kill your fish without question. As you can tell, chlorine is usually beneficial for humans, but not so much for the fish and plants in your aquarium.
Remember folks, chlorine is horrible for your fish no matter what. Under no circumstances can you fill your aquarium with untreated tap water. You need a good dechlorinating agent or water conditioner to get rid of that toxic chlorine. Keep your fish safe by using the best Dechlorinator for your aquarium. The 6 above conditioners all make for good choices in our opinion.
