For copper medication on a separated tank, just a empty tank where there isn't any coral, Live rock, live sand? Do I need to bring down the temp. Salt water? Where can I get the seacham cupramine? Still need lights?

Here are some of the picture.... Someone say causes by the coral, so do I remove the it?

Copper? How to ?

Any way to cure?

please someone advise me, why black spot and how to cure?

Most livestock are tolerant to some levels of water characteristic for marine water hobby....So may I know what is critical to regularly check?
