What happens if chlorine is in aquarium water?
Chlorine is a chemical that water suppliers use for disinfecting drinking water. It also helps eliminate any harmful disease-causing microorganisms present. Chlorine exposure may benefit human beings but it is harmful to the health of fish and other aquatic creatures present inside the aquarium. Chlorine maybe present in aquarium water. This will adversely affect the living organisms in an aquarium. It will also harmfully impact fish and plants. So, are you wondering how to remove chlorine from aquarium water? Let’s find out.
Chlorine usually finds its way into aquarium water when the tank is filled or topped off with tap water. A lot of aquarium owners don’t know that their water contains chlorine, and they never really test it according to their local water. You must know the water quality you are using for your aquarium to keep any harm from happening to your aquatic environment.
Impact of chlorine on fish
Fish and other aquatic organisms are highly sensitive to chlorine. Here are some of the primary effects of chlorine on fish:
- Gills Damage: Chlorine can damage the gill tissue of fish, leading to respiratory difficulties. Chlorine levels higher than the natural level can cause fish and other aquatic creatures considerable health problems. For example, when chlorinated water enters a fish’s gills, it affects the blood oxygen level in different ways. This makes them capable of absorbing less oxygen, which eventually causes stress or death.
- Skin Agitation: Chlorine can also irritate the skin and mucous membranes of the fish which causes inflammation. As a result, fish suffer from susceptibility to diverse diseases.
- Behavior: Presence of chlorine causes abnormal behaviour in fish such as gasping for air at the surface, swimming erratically, and hiding more or less than normal.
- Long-term effect: Fish subjected to long-term entry into chlorinated water face damage to the immune system. This causes infection and other diseases to spread inside their body.
Effect of Chlorine on Aquatic Plants
Chlorine is not the only substance that poses a danger to fish, chlorinated water does not sit well with aquatic plants either. How Chlorine Can Hurt Your Plants:
- Cellular damage: Chlorine damages the cells of aquatic plants and causes them to wilt and die.
- Stunted growth: Chlorine does not let plants grow properly, thus welcoming other problems.
- Causes algae growth: Chlorine can also help algae to grow more in numbers as it throws off the nutrient balance.
If you want to test for chlorine, consider the following:
- Chlorine test kits (available at pet stores and online) are a simple way to test your water.
- Check your local water quality reports, which usually specify chlorine levels.
- You can also use your nose, as chlorine has a distinct smell. If your water has the smell of bleach, there is a good chance that it will contain chlorine.
How to Remove Chlorine from Aquarium Water
If you determine there is chlorine in your aquarium water:
- Using Dechlorination Products: There are many commercial dechlorinators out there that can neutralize chlorine immediately. If you want the best results, always follow the manufacturer’s instructions.
- Letting Water Sit: If you fill your aquarium with tap water, letting it stand for 24-48 hours will help the chlorine evaporate. Nevertheless, this technique may not work against chloramines, which are more stable.
- Installing an activated carbon filter: in your aquarium setup can help remove chlorine and other impurities from the water.
- Using a reverse osmosis (RO) system: can provide pure water free from chlorine and other harmful chemicals.
Preventing Chlorine Issues in Your Aquarium
