Review: Excellent product! - I've used this product for about 10 years, ever since setting up my first fish tank and find it very effective in that tank and a much larger one I now also have. My shubunkins were hatched naturally outside in a garden pond which had bought fish in, and I brought some of the tiny fish inside over a winter 4 years ago. They have thrived and grown to much larger fish now. They seem to stay really healthy and the water quality is also good between changes. I think I must acknowledge the beneficial part Strees Coat plays in all this.

### ⭐⭐⭐⭐⭐ Excellent product!

### ⭐⭐⭐⭐⭐ Almost perfect except
*by A***P on 20 March 2017*

Overall this is a great product and does it's purpose but I Will not buy this product again, I'm switching to seachem products. This is great for beginner fish keepers. I have large tanks and this isn't very concentrated so I had to use almost half the bottle the first time I used it.. it's great for people who have less than 100gallons and don't do weekly water changes. I have lots of piranhas and cichlids such as oscars. If this came in a more concentrated form and gave me more than just a stress coat, I would stick with it.
