API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

Don’t buy this . So upsetting.This kill my koi . Oh my god . 7 my beautiful is dead.

Fish are happier...!

You have to do some calculations to get to water/ conditioner ratio right but overall a fairly simple process. The cost seems a bit high at first but the 1 gallon bottle goes a long way for me, (depends on the size of your pond I guess). This product has always worked well for me with no issues. Ive been using it about 5 years now.

Great product for my pond**

Seems to work OK

I used this everytime I add water to our Pond.

Excellent, get through loads in my koi pond.

The bundle for $89.99 only includes a tiny 32ounce bottle(tiny quarter gallon) of stress coat. If you bought the 3 items in the bundle separately they would only be $54.50! Conveniently the image of the 32 ounce bottle looks just like a full size gallon jug, but in person its miniaturized.

Worked as described, good results

I use it with my weekly water changes in my 1800 gallon pond. Koi are doing well with it.
