Hi 3reefers, We've got 3 boxes of Evolution Aqua PURE Marine to give away to 3 lucky 3reef members. We are the first retailer in the United States to carry the product and we're looking for 3 3reef members to try out the product and write about their experience using it here on 3reef. Just use the product until it's gone and relay your experiences in a separate thread. That's it. If you're interested, send us a private message with your name and mailing address. The first 3 members to respond will receive a FREE box of PURE Marine bacteria/enzyme balls for you to treat your tank.
