Well if any of you looked at my old post about the Algae fix its definately not why my fish died. It because i just noticed that my fish have marine velvet... Thats probly why it died w/o poor water quality. As of now i have 3 fish left in a quarantine and im dosing them with copper and Ich-X. They have been in there for about a week now and they look healthy. How long should i leave them in there?
