Best Aquarium Water Conditioner: The Ultimate Guide

Many inexperienced aquarists make the mistake of overlooking proper water conditioning before adding fish to an aquarium. Most people understand that fish are sensitive to water temperature fluctuations. After adding water into an aquarium, most people would check the temperature, but often disregard the fact that there is chemical additives in tap water. The tap water in many cities are treated thoroughly with chemicals to make it suitable for human use. It may be great for showering and washing dishes, but not exactly suitable for fish to swim in. In fact, it can be highly toxic for fish.

The chemicals in unconditioned tap water can cause a lot of harm to the fish. A common chemical additive in tap water is chlorine and chloramines. High levels of these chemicals can destroy the fish gill tissue, and prevent the fish from breathing. In fact, even low levels of these chemicals will irritate the fish tissue and cause harm to the fish. Many fish die as a result of unconditioned and poorly conditioned water, and the ones that do survive experience a lot of stress. Therefore, aquarium water should be properly conditioned before fish are introduced into it. Conditioning water may sound complicated if you are not a scientist. Fortunately, there are many aquarium water conditioners on the market that will make the process of making water safe for your fish very easy.
