I am not sure where to write a review of KP Aquatics but these guys are absolutely legit. Everything I have gotten from the from the last three shipments have exceeded not only quantity but also quality. Used to buy from saltwater fish.com but will never ever again. KP has the best rock I have ever seen and I am a master scuba instructor from PADI and we used to own a house in Marathon Ket, FL and this stuff is incredible!!!!!!! I cannot say enough good things about these guys other than I will never order anything from anybody else again!!!
