Bio brick in QT with copper treatment

[tbs246]

I put a bio brick in my QT that has copper in it. Since I put it in, the copper level reduced greatly from 2.0 to 0.91 ppm. I’m new at this, and I think the bio brick is absorbing the copper. Am I correct, and if so, what is a good alternative to keep ammonia low?

Water changes! 100% every 3 days.. Ditch the bio block, it has nothing to do in there..

Have a good look at this guide to quarantine. This is the one that I am replicating in my own setup.

Here's current quarantine protocol:

Foam sponge is recommended as rock or porous, ceramic biomedia can absorb copper and change it's concentration.
Frequent water changes may still be needed if your biofilter is not mature and not efficient enough.
