Zoas melting

10 ppm of copper is huge. are you sure it's not in the range of .10?

In any case, anything showing up on these tests is not a good sign since they are not as precise as pro lab machines.

The level to kill ick is .120 usually. What killed many of my corals we at .035 or around that since this is only an estimate.
