Hello. We have a reef tank we started a few months ago. We bought a couple fish and some corals. Everything was going well then we ended up with ick. We set a quarantine tank and have started treating it with hyposalinty and copper power. Once we get past this and starting buying fish again what is a good regimen to treat new fish. We have metroplex, kanaplex and focus. Do I treat with all 3 at once or do it separately? We also have garlic guard to mix with the medications
