water for Aquarium
Tap water is available almost anyone keeping an aquarium and is almost always going to be fine for your fish. If you’re beginning a freshwater tank, tap water is going to be perfectly fine unless you are sure the tap water in your space is of horrible quality. Still, you do need to be aware that if your tap water is from a municipal water supply, or if you have a holding tank for your water supply, you probably have chlorinated water, and you’ll need to use a chloramine remover to create the water safe for your fish tank, depending on which compound is used in your water system.
Some of the people might think rainwater is clean when they live far away from the cities. Rainwater is always lacking in necessary trace elements to keep the fish healthy, as well as those necessary to help the water maintain chemical balance. The truth is that the pollution can affect a much more significant area than you think. It is not a good or not safe source of water at all for aquarium fish.
Bottled drinking water is another choice for a fish aquarium. Bottled water is often not tested or regulated so the water parameters are unknown. Also, bottled water often has vitamins, preservatives, colors, flavors, or other additives added to make the water more appealing. These can be devastating to your aquarium. It will cost a lot more, and you will have to pay attention to the ingredient on what is in the bottled water. Some of them might not be just H2O, and they can have additives that can be deadly to the fish.
