API GOLDFISH PROTECT Aquarium Water Conditioner 4-Ounce Bottle

Work great for my fish

We've had issues with our goldfish dying off of disease with either new goldfish or newly introduced goldfish. We've been using this with our latest batch of goldfish and they've stayed alive and healthy longer than any other fish we've had. It works great and we'll continue to use it forever, highly recommend!

Comes with a cap with measurements, convenient.

As advertised

Works well, but I wish it came in a larger size. I have a 20 gallon that it works well in. The last one I bought had a cracked cap so I had to recycle one from another bottle to make sure the liquid didn't evaporate after I opened the seal.

Bought this product after the local fair for my gold fish and we loved it!! It really made my gold fish last for a very long time! My fishies loved it

When I put tap water And I add the amount that bottle recommends. It works perfectly The fish are happy.

Thanks great product wish drivers would knock on the door thanks
