To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Loads of my fish died when I used this. I stopped using it and thought it might have been coincidence, all my other fish have been fine....until recently I used it again and more fish have died. Not convinced this is a genuine product. Avoid.
Been using this product for years! this is the first time I purchased this product in Gallon size from Amazon and I'm shocked that there is no seal. This is unacceptable , I have a 120gal tank and i don't feel safe using this.
I just used this product on March 16, 2013 and one of fish died. I thought the fish died because of age. I used the product again on 04-04-2013 and I had 5 fish die this time. I took the product in to Pets Mart and they said this product was contaminated and it was the reason why my fish were dying. I am not happy at all!
