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.

Review: The best value for tap water treament - I love all of the API products, especially their easy to use test kits. This product is great as well. Regardless of which size you buy of their tap water conditioner, it is the best value of reputable brands that will treat all tap water for your pond or tank. It only requires 3 drops per gallon you add to your tank. It removes chlorine, neutralizes chloramines, and helps detoxify any heavy metals in your tap water. Some more expensive products will claim to also include things to help your fish maintain their protective slime coating (and cure male pattern baldness and perhaps ED). If your fish are healthy, and your tank's water parameters are maintained well through weekly water changes and good filtration, those other ingredients are useless. (The "Special Sauce" is just ketchup, mayonnaise, and relish.) If your fish have sores or other health problems, then find the cause, fix it, and treat them with something besides a tap water conditioner if needed. Like every other tap water treatment API's instructions first tell you an amount of the product required to remove chlorine, and then in smaller print below say to use 2 to 3 times as much to also neutralize the more toxic chloramines that may be added during the purification of your water. I don't know why the companies that make these products won't be honest and say up front to use the higher amount, and then in small print say you can skimp and use less if you want to save money and risk the health of your fish. If you have confirmed with your local water authority that they do not use chloramines during their treatment or your water, then it only requires a single drop per gallon to remove chlorine. I did not bother to call my county water authority, since I had no way to confirm that the person who answered the phone would know chlorine, chloramine, nor chloroform for that matter. from their own colon or a hole in the ground. Even if you personally spoke to someone that could tell you for dead certain that chloramines are not being used, they are not going to text you if that changes in the future. Unless you are the person in charge of that step of water treatment for your area, the only way to know for certain if your water was safe for your fish with only a single drop per gallon, is if you use one drop, then test that water for any detectable ammonia that is the treated water. The chloramines contain a small amount of ammonia. Then you would know it was safe to add to your tank without causing them irritation and inflammation of their gill tissue. It is much safer to simply to add 3 drops per gallon. More doesn't hurt anything, but it's just wasted. To refill my tanks, I keep a pair of 5 gallon plastic bottles that were used for filtered / spring water. After I fill my tanks, I add the tap water treatment to the jug, refill it, and let it sit until I need it. This allows the conditioner time for its anti-heavy metal ingredients to work fully. It also lets the water come to room temperature, since 5 gallons of icy cold tap water in winter can cause the temp to drop in a 55 gallon tank. Perhaps more importantly, the water lines in many places are old and require frequent repairs or expansion. When repairs are made to water mains, they sometimes add extra chlorine disinfectant at the repair site to insure that any bacteria that might have gotten introduced to the main are killed and cannot grow and contaminate our drinking water. While I cannot normally detect a smell of chlorine in my tap water, I occasionally notice that it smells a bit more like a swimming pool than tap water. If more chlorine than normal is in the tap water, then more neutralizer would be needed. Most Chlorine will gas off on its own if the tap water is left uncovered for 24 hours, but Chloramine will not. When they disinfect a repair site, they are normally only using chlorine. By leaving the water I will add to my tank sitting for at least a day, then I am positive that it is always safe to add to my tank. I have had people ask me before if they can add the conditioner to the tank and then use a water hose to refill their tank. I don't normally recommend this because many of our fish are conditioned to come to the part of the tank where we are standing and adding water, because they think food will soon be added as well. If you add the conditioner to the tanks water rather than to the tap water first, then the tap water from a hose will take a short while to react with the treatment additive. Temporary short spikes of chlorine won't kill your fish, but cumulatively over time, it's not good for them either. Also unless you have a hose that is certified safe for drinking from, it can leach harmful chemicals into the water you're adding to the tank. If you are using a normal garden hose to refill your tank after water changes, at the minimum you should run water through it first for a few minutes to make sure that any that has been standing in the hose is washed out. ## Features - Contains one (1) API TAP WATER CONDITIONER Aquarium Water Conditioner 16-Ounce Bottle - Neutralizes chlorine, chloramines and other chemicals to make tap water safe for fish - Prevents tap water chemicals from causing gill destruction, tissue irritation and fish death - Super strength, high concentration formula - Use when adding or changing water and when adding new fish to freshwater and saltwater aquariums - Add 1 ml. for each 20 gallons of aquarium water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004LO9KSY | | Allergen Information | Apple Free | | Best Sellers Rank | #904 in Pet Supplies ( See Top 100 in Pet Supplies ) #2 in Aquarium Water Treatments | | Brand | API | | Brand Name | API | | Customer Reviews | 4.7 out of 5 stars 27,141 Reviews | | Global Trade Identification Number | 00017163003526, 10017163003523 | | Included Components | 1 Bottle 16-Ounce | | Item Form | Liquid | | Item Type Name | Aquarium Water Conditioner | | Item Weight | 1.2 pounds | | Liquid Volume | 16 fluid ounces | | Manufacturer | Mars Fishcare | | Manufacturer Part Number | 52C | | Model Number | 52C | | Number of Items | 1 | | Number of Packs | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 017163003526 | | Unit Count | 1 Count | ## Product Details - **Brand:** API - **Item Form:** Liquid - **Item Weight:** 1.2 pounds - **Liquid Volume:** 16 fluid ounces - **Number of Packs:** 1 ## Images ![API TAP WATER CONDITIONER Aquarium Water Conditioner 16-Ounce Bottle - Image 1](https://m.media-amazon.com/images/I/51VRitTWE4L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the difference between the 1 gallon item at $37.28 and the 128 ounce item at $19.46?** A: $17.82 **Q: Can I use it for the water I use to water my plants? My plants don't do well with my tap water. Thanks :-)** A: I add this before every watering for medical cannabis plants. 1 mL per 5 gallons of water. Had severe problems before using this. **Q: What's the difference between the tap water conditioner, the stress coat conditoner & the stress zyme. I'm confused, do I need all three for my biorb?** A: Looking at the ounces needed per gallon, the stress coat treats 60 gallons per ounce while the tap water conditioner treats 600 gallons per ounce. It looks like the stress coat does more things to protect the fish, but the tap water conditioner will treat more tap water per bottle. **Q: I have had this product for about 2 weeks. In the past few days it began to smell reallly bad. It smells like old faithful. Does anyone elses smell?** A: i keep mine in the refrigerator to avoid that situation from happening. It is probably spoiled. First, check the expiration date on the bottle, if it is still supposed to be good, you may want to look around the storage area you had it in for local heat sources that can sour it, such as: periods of direct sunlight during the day, sitting in front of the heat vent, etc. These can spoil the product in short order. Like I said, I keep mine in the fridge just to be safe, (all my liquids for my tank are in the fridge, even tho they do not require it.) I hope that helps. for what it is worth, the smell I get from a fresh one has a tang of aloe vera to it, smelling like a swimming pool kinda smell, minus the chlorine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Must-Have for Aquatic Health! *by T***O on February 17, 2025* 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.

I only need to clear 1 quart to 1 gallon (4 q), but this stuff is made for large amounts. For chloramines, you add 5ml per *30* gallons. The top measures 5ml. Thus I only add a literal *drop* from a 1ml syrine into my 1qt buckets. For me, it's a great value - it'll last forever, lol. For aquariums, obviously less time, but the price per oz of this was better than the other conditioners I saw, sooo it seems like a good value for all. ## Frequently Bought Together - API TAP WATER CONDITIONER Aquarium Water Conditioner 16-Ounce Bottle - API STRESS COAT Aquarium Water Conditioner 16-Ounce Bottle - API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria 16-Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/742756940-api-tap-water-conditioner-aquarium-water-conditioner-16-ounce-bottle](https://www.desertcart.com.ar/products/742756940-api-tap-water-conditioner-aquarium-water-conditioner-16-ounce-bottle) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-22*
