Think I ****ed up, got a new tank and putted water inside to test leak, I used a old pump to empty the tank . The problem is that this pump and the plastic vinyl tubing to get the water out the tank has been used in a tank with copper mediation before , that pump and vinyl tubing or regular tubing has been dry for about 2 years . Have I ****ed my new tank ?was planning mixed reef , anyone thoughts is it too risky ? Please any thoughts
