It likely has absorbed copper and other elements and in essence you would be reintroducing any of those elements to new setup. Not worth it- Start with new

Yeahh that what I am worried about. I've heard others have tested the Matrix media and confirmed it does not absorb copper levels. It suppose it probably does even a little bit.

As they say, it's complicated. Matrix is supposed to be inert - that means it won't absorb copper. However, copper can also ADSORB onto surfaces, and the more surface area, the more it can do that. Ionic copper is more prone to doing that.
Here is a trick to test for this (and to clean the matrix out better). Put the matrix in a bucket of RO water. Add some white vinegar to drop the pH below 6. Aerate the bucket overnight. The next day, test the pH and the copper. If the pH is still low and no copper is reading on the test, you can rinse off the matrix with RO water and you are good to go. If the pH jumps up or you get a reading on your copper test, rinse the Matrix off and repeat the process.
