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.
I purchased a couple of new fish and within a week my entire tank had ick. Since I didn’t want to destroy my biological filter I increased the water temperature, did 25% water changes with reverse osmosis water and started double dosing daily with StressGuard. Within a week every fish was ick free and happy. Seachem products are by far the best on the market.
