API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

I have a 6500 gallon Koi pond I add this to the water every single time I top off because I have city water with chemicals and chlorine,. It has kept the water quality perfect and balanced. I have never had an issue using this product for many years. I would not go without it.

stress coat is a must for ur fish. i use it when necessary

Our go to for koi pond. Never fails.

I actually calculated this to use in my 60-gallon tank so it lasts a really long time! API products work really well and the prices are really reasonable. I would recommend.

In two weeks I. An see an improvement in my plants. Leaves are no longer dropping and there isn't of new growth. I'm using this forever. I'm using this for cuttings and floral bouquets.

I have an outdoor turtle and fish pond and I put this in to add water out of the hose and I have never had an issue. Would highly recommend.

Always like to have this on hand in case of an emergency water change! I have seen the difference in koi behavior when using vs not. I like to add immediately when I begin filling and make sure to use the hint on the bottle -- mix the measured amount with pond water in a bucket first then evenly distribute. Happy I got the big bottle this time since the smaller bottles only last one or two times for my pond size.

I use this when I need to do a water change in my pond. Although my water is filtered it's good to be careful and use this to keep chlorine out of the water change.
