APIStress Coat Fish and Water Conditioner Size: 16 Oz

I use this in my 55gallon and it works just fine!

I am a big fan of this companies fish stress coat! We have a medium sized outdoor koi pond in Florida. We have to refill the water often due to the hot Florida sun. We use 2 capfulls every water refill. Our koi fish are healthy and beautiful. We will continue to use this product. When you have an outdoor koi pond and you find a great product that does what it says, you stick with it.

Like another reviewer, the product that I received (through Amazon seller: PondandGardenDepot.com) does not say Stress Coat PLUS, however if you compare the labels, it's actually the same thing in a slightly different package. What I received was API Pond Stress Coat with the blue measuring cap. I received what I expected, which is a stress coat product that removes chlorine, chloramine, and ammonia from tap water, and has aloe vera and other ingredients to help replenish slime coat and reduce stress. A quick Google search tells me that the PondCare brand is adopting the API Pond name (these are both brand names of Mars Fishcare). They apparently decided to drop the "PLUS" from this product's label during that change, but it still works as expected.

I use this all the time when putting anti chlorine in the pond...This bottle is too small for me as I have a large pond and need to use it often.The product however is very good...

Easy to use . Worked great .
