Fish seem healthy and active during use. I love all of the API products, especially their easy to use test kits. I've used every product on the market and this is the most AMAZING MUST HAVE PRODUCT! My water is crystal clear like the first day i filled it and i could be happier. You have to understand when to use this product, and what is is used for.

"Keep testing the ammonia."

I know you are going to want to add more chemicals, etc. I have been battling cloudy water in our small aquarium for two months. I tried it without the water change and really didn't make a difference. My water is crystal clear again, and it smells like a healthy fish tank again. During cycling you will be using often. Just an idea incase someone doesn't have a spare dropper. I have a great pump and uv light but still had cloudy-ish water.

"Did a tank cycle."

I have been battling cloudy water in our small aquarium for two months. If you have a freshwater fish tank, I highly recommend this product. I've using this for my betta for several years with every water change. I've used API water conditioner before and it works well. I have a 5 gallon tank, so that number was waaaay too high for me. I love all of the API products, especially their easy to use test kits. I'm sold on this, I've tried SO MANY and wow.

"Really good product!"

I hope I made the right decision, Betty is our family pet and is really loved!

I tried it without the water change and really didn't make a difference. Fish seem healthy and active during use. I was sort of nervous buy this product and trying it out.

API Final Thoughts

"I love this product."

Fish would die occassionally every few weeks or so. Pictures included to see the difference. I have been battling cloudy water in our small aquarium for two months. You need to buy an eye dropper for this. Use a heater and crank it to 82 degrees again without fish in the tank. I've had my fishy for 5 years now and I would say it's ALL because of Fluval. Fish possess an antioxidant defense system to reduce the negative effects of ROS.

Just an idea incase someone doesn't have a spare dropper. I have been using API on his suits for 3 weeks now and so far so good. But the septic tank bacteria did nothing. During cycling you will be using often. I have had aquariums for 40 years and have always used their product Cycle. No exaggeration-- literally cleared overnight.

T. H. Marine U216-FW Final Thoughts

"It really works."

The afternoon I received this product I added half a dose to each aquarium. It is just as good when compared to other brands of conditioner. When they disinfect a repair site, they are normally only using chlorine. It is much safer to simply to add 3 drops per gallon. I read another review for this product saying they were using API for this purpose. This product is exactly what it says it is. This is the 5th since I put in the product and my tank is crystal clear.

"So easy to use."

API Stress Coat is a phenomenal product. It is just as good when compared to other brands of conditioner. This is my absolute favorite conditioner I have used for all my aquatic creatures. My filter including polishing element could not clear it up. More doesn't hurt anything, but it's just wasted. Ever since I made this purchase, my fish are not dying at all. The water we get here in SoCal is hard with chlorine in it.
