Good water quality is the key to a healthy, beautiful aquarium. Tap water contains chemicals, such as chlorine and chloramines, which make water safe for drinking, are highly toxic to fish. High levels of these chemicals destroy fish gill tissue, preventing the uptake of oxygen which can lead to fish death. Even low levels irritate delicate fish tissue. Tap water must be treated before adding fish to make sure fish remain healthy. API TAP WATER CONDITIONER Aquarium Water Conditioner instantly removes chlorine and neutralizes chloramines. It also detoxifies heavy metals in tap water. The formula of API TAP WATER CONDITIONER incredibly concentrated. You only need up to 3 ml to treat 10 gallons of water.

    A Must-Have for Aquatic Health!
    I’ve been using API TAP WATER CONDITIONER for a few weeks now, and I’m extremely impressed with its effectiveness in keeping my aquarium water clean and safe for my fish. Here’s why I’m giving it a 5-star review:
    1. Perfect for New Aquariums and Water Changes:
    I’ve recently set up a new tank, and this conditioner has been a lifesaver. It quickly removes harmful chlorine, chloramine, and heavy metals from tap water, which could be toxic to fish. It ensures the water is safe to use without waiting for the water to sit for days.
    2. Safe and Effective for All Fish Species:
    Whether I’m adding new fish to my tank or doing a routine water change, I feel confident using this product. It’s safe for all types of freshwater fish, including my delicate species. I haven’t noticed any signs of stress in my fish after water changes, which speaks volumes about the quality of this conditioner.
    3. Easy to Use:
    The API TAP WATER CONDITIONER is super easy to use. I simply add the recommended amount per gallon of water, and it instantly works its magic. No hassle, no mess—just pour and go!
    4. Great Value for Money:
    Considering the price and the amount of product you get (16 ounces), this conditioner is a great value. It lasts for a long time since you only need a small amount with each water change, making it an affordable option for any aquarium owner.
    5. Fast Acting:
    The conditioner works fast! I can fill the tank with treated water and immediately begin acclimating new fish. I’ve had no issues with cloudy or unsafe water when using this conditioner, and it’s consistently kept the water quality at its best.
    6. Trusted Brand:
    API is a well-respected brand in the aquarium industry, and it’s a name I trust when it comes to my fish’s health. Their products are always reliable and effective.
    Final Thoughts:
    If you’re an aquarium owner, whether you’re new to fishkeeping or a seasoned pro, I highly recommend the API TAP WATER CONDITIONER. It’s safe, affordable, and does exactly what it promises—ensures clean, safe water for your fish and keeps them happy and healthy.
    💯 Five stars – a must-have for any aquarium enthusiast!

    Been using for years. Works excellent!
    A little goes a long way. The bottle is very good quality. Use when doing water changes. I add a little before filling up my tank and pond. And then I add a little after it is done filling. I add directly to the tank. and use a fill hose to fill it directly from the tap. If used correctly your fish won’t die. If they do die it’s probably not the chlorine. More than likely it is from a difference in temp which causes them to go into shock. If you make sure that you’re putting close to the same temp water in there then it should be fine. Works with tropical fish, goldfish, and other breeds. It also can be used for your birdbath or for use with other pets that require water like turtles, birds, and hamsters. You don’t have to overdo it with this product. Just follow the directions or add a tad extra if you are filling directly from a tap. I have used a lot extra on accident a few times and it doesn’t hurt the fish. Just make sure you don’t dump the whole bottle in there and you will be good to go. A must have for pet owners and fish keepers!

    Removes chemicals in drinking water
    I noticed my african violet leaves were drooping without an apparent cause, but it was suggested to me that it was being caused by chlorates in my drinking water. I called and found that chloride and chlorates were in the water. I bought this product to remove those elements before watering. It’s proving itself effective because my plants are looking better. Very simple to use…a few drops in a gallon of water. The bottle size is small but you only need a little bit at a time. The water is cleaner sans mentioned chemicals, water is clear, and my plants are healthy and happier. The price is extremely fair, there are choices of different sizes, and I will buy this product again.

    The solution in here seems to work better than the other solution that I used to have from the pet store, even though the bottle is smaller I would purchase this again

    If you own a large aquarium 200l+ this is an absolute god send, so little needed this will last a life time. Decant into a smaller easier to dose container and its amazing.
