API Tap Water Conditioner, 16 fl oz - Super-Concentrated Dechlorinator for Freshwater, Saltwater & Planted Aquariums

I used this product in my koi pond, when adding more water to the pond. I have had this pond for 4 years and do routine maintenance. I came out the next day to feed my koi and all 5 were dead. I have had aquariums and ponds most of my life and am 70 years old, so am very knowledgeable in my hobby. Did absolutely nothing different, than I always have and the only possible reason for my fish dying is this product. My fish were my pets they ate out of my hand and would swim allowing me to pet them. After talking with my friend that owns an aquarium store for over 50 years agreed. I strongly advise against anyone buying from this company or this brand. I am no longer going to have a pond, am in the process of having it dismantled.

[This review was collected as part of a promotion.]  I am not used to this type of top water conditioner. Our fish is actually my brother's fish. And one of them died before we got the chance to put them in the aquarium. The other fish that was able to be put in the aquarium has been surviving so far and it's been 2 to 3 weeks now. We only used the tapwater conditioner in the tapwater and then we put the fish on it so far so good. It doesn't smell like chlorine. The application was smooth. I like that you can use the cap as a measurement tool. Is just liquidy in terms of texture and it's clear. You can't really differentiate from regular water. 

[This review was collected as part of a promotion.] API Tap Water 💦 Conditioner has a sleek packaging that fits well next to my fish 🐟 tank to grab for each tap water tank change. The water clarity is great and “Dumbo”, seems to really like that I care enough to make sure his tank is tip top shape for his clean environment! Storage is simple as this bottle is slim and easy to keep in a cabinet or as I do next to the tank with the rest of the supplies to keep a healthy tank .

[This review was collected as part of a promotion.] I use it to start a new tank or replace water. This has been great for my beta fish tank, they are loving it. Having the dosage cap helps to make sure that I am not adding too much and it's safe for my fish too.

Product was great arrived I damaged and working well for tanks

Great staff for my fish tank.

This water conditioner is fantastic! I have purchased it multiple times. While I don't use it for a fish aquarium, I do use it for my succulents and houseplants. I watched a video on YouTube where someone used it for their houseplants, and they were thriving and looking beautiful. I simply add a capful of this water conditioner to a pitcher of water, and my plants are flourishing!

Great product easy to use has not harmed fish or plants.

[This review was collected as part of a promotion.] This is trusted brand and product. My husbands used this brand for many years for his aquarium. Great quality, always works and never had any issues.

[This review was collected as part of a promotion.] The before photo shows how cloudy it had gotten in the tank and with one water change we have a clear, fresh tank. The fish are happy and so am I. The product was quick and easy to use. The bottle allowed for easy dispersion.
