Fish are among the easiest pets to take care of. You simply purchase a tank, add some water, add a few fish, and feed them. Sounds pretty simple huh? It does sound simple but there are a few factors that can complicate things. You want to be sure you choose fish that can live together in the same tank, feed them the right food, and it’s very important that the water provides the right climate. This water can come from a variety of sources, including ordinary tap water.
Now, there are those people out in the world that feel tap water is horrendous and they certainly won’t drink it, let alone put fish inside it. I mean, it’s full of all kinds of chemicals and things that are harmful to me, right? They’d be harmful to the fish, too – right? Umm.. that would be “no” and “no”.
Let’s take a look at the basics of how that water should be in a Freshwater Tropical Fish Community tank. The temperature of the water should range from 72-82ºF with a pH ranging from 6.5-7.5. The nitrates should be <50 ppm and the ammonia and nitrates are best at zero. The water's hardness should be 4-12GH. Each of these parameters should be balanced with one another. If you use tap water you might have to add some conditioner to it in order to reach this goal. If your tap water comes from a well it might already be balanced so you should always check these levels before adding any fish to the tank.
Many pet supply and fish supply stores stock these conditioners regularly. The fastest acting ones are the brands you can put into the water as you load it into the tank. This is perfectly safe for the fish. It will not cause them any illness, mental or physical. It will not damage their bodies in any fashion. Make sure whatever you choose contains a dechlorinator or a chlorine remover as it’s the chlorine from the tap that can cause the hugest amount of problems. Copper, phosphates and pesticides are sometimes found in tap water as well. You need to counter this is some type of balancing agent, usually found in tablet form, at the store. Any of these items, when reading too high in the water, can cause stress and other related ailments to the fish. Almost always, you needn’t worry about any of these issues as most tap water is pretty well balanced and perfect for the fishies.
There are other sources for aquarium water other than the tap, including distilled water, rainwater, and reverse osmosis water. The main problem with collecting rainwater is the risk of also collecting pollutants and debris. It is an especially bad idea in areas that frequently experience acid rain. While using RO water might sound like a good idea, it’s really not. You see, drinking purified water is great for humans, but rather bad for fish. You would have to remineralize and oxygenate the water in order to maintain the right chemical and organic balance.
Feed the floaties, keep their home comfy cozy and fill it with well balanced water and there shouldn’t be any issues whatsoever when it comes to their health. Remember for fish: tap water good, distilled bad.
