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've used zoo planc before I bought this and truly speaking the first product was so good that it made me buy Phyto Planc of the same brand. Guys I'm a buyer and not an agent of aquatic remedies, my experience is terrific. It really helped a LOT. Thanks.
