Coral Dip is a very important addition when it comes to owning a reef tank. It can cause unnecessary coral loss if a new member is added to the tank with pathogens that could potentially harm other corals. Don't risk losing losing corals. Treat them first before adding them to your tank. We carry Coral Rx, Brightwell Aquatics and Two Little Fishies brands. Make sure to follow instruction to ensure you are using these products accurately. If you have any questions which one may be right for you don't hesitate to contact us.
