Fish can be some of the easiest animals to take care of. You buy a tank, throw a bit of water in, add fish and feed. Pretty simple, isn’t it? Of course, there are a few things that make it a little more complicated. You want fish that can get along together in the same tank, you need to assure you’re feeding the pretty little floaties the proper food and, most importantly, you need to make sure that the water is perfect for their climate. Water can come from several sources, including good old-fashioned 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.
You should have no trouble finding these conditioners at fish or pet supply stores. You can find fast acting conditioners that work as soon as its added to the water in the tank. These conditioners are absolutely safe and will not harm your fish. These conditioners will not damage their bodies or cause any physical or mental illness. Just make sure you select a condition that contains a dechlorinator or chlorine remover because it’s the chlorine in the tap water that causes the most problems. Additionally, pesticides, phosphates, and copper are sometimes found in tap water. These substances have to be countered with a balancing agent that is readily available in a tablet form from a pet supply store. When you test the water, if any of these substances have a high reading, the fish can develop stress or other ailments. In most cases, tap water if fairly well balanced and you won’t have to worry about any of these problems.
Other alternatives for water in the tank include rainwater, distilled water or reverse osmosis (RO) water. The problem with collecting rainwater is the pollutants and miscellaneous debris that could be in with the water, especially in areas that have acid rain. This sounds like a good idea, but it is not. With distilled or RO water it is almost pure water with no additives. This is good for humans, but bad for fish. With either of these latter choices you would need to oxygenate and remineralize the water so that the proper chemical/organic balance can be maintained.
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.
