API Stress Coat Water Conditioner 64 fl.oz, Pack of 2

It is exactly as advertised. Because my gold fish were developing white spots, I am now adding this to my pond after adding city water to it. Dont know if the spots disappeared on their own or it was this product, but I am going to continue to use it!

Great!

When I add (hose) water to pond

awesome

Now this is a product that I would purchase again for conditioning of water for my fish. Save time from running back and forth to a fish store to get a small bottle.

This product is great for my goldfish--especially when adding water.

good deal on a good product-thank you

Use this product for outside koi pond and aquarium Love it keeps fish healthy

Did the job!!

always good quality, this is something you can trust on the koi fish pond.
