API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

Great product

Great product excellent service

I have used Stress Coat for years in the aquarium and in that situation it is a reliable performer, although I tend to use Amquel now as it removes more bad things. I digress. I have never used Stress Coat in a pond as for de-chlorination purposes I use a three canister water purifier. However, this summer I had a frightening ammonia and consequent nitrite spike in my pond. Usual water changes, more quick fix bacteria added, but to no avail. I saw that Pond Stress Coat was supposed to remove ammonia. The API web site was suitably vague on the subject, but I thought I had little to lose. Added 1.25 litres of Stress Coat to 5000 gallon pond. I took a water sample 5 minutes later. The ammonia was gone. Strangely enough, so was the nitrite, which I do not understand. I would have thought time would need to pass for bacteria to remove the remaining nitrite, but Im not complaining. A very good detoxifying additive then. The only downside was the Amazon Prime delivery. Ordered Monday, arrived Thursday, not something fish keepers will appreciate.

Great product. Helps me change 1000 gallons per week (my koi won’t stop growing!)

My Koi have not developed skin burns after adding new water and are lively afterwards.

Great stuff. Works great in koi ponds and aquariums.

I can tell a marked difference in my Kois health this year since I have started using Stress Coat.

This is my go to when doing larger water changes in my koi pond. The stress coating helps keep them healthy. And its cheaper to buy on Amazon than at Petco or PetSmart, so Im a happy camper.

Very fast delivery I like that

Can’t go wrong buying this by the gallon on Amazon. I’d go broke if I had to buy it at a pet shop.
