New Reef Ich Problem

[Aquattro]

CP is chloroquine phophate, said to work against ich, velvet and brooklynella. I've just heard about and used it recently, and I'm happy with the results. I know that it's fun to come up with reasons not to run a q tank, I did for 12+ years. It always worked, until it didn't. I lost about $1000 worth of fish in a week over adding a fish I didn't really want in the first place, but made an impulse purchase. I will not do that again. Once I've added my new treated fish, I will not add another fish without treating it first. This will likely mean not adding another fish, since I really don't want to quarantine. But if I find a must have fish, I will.
