Slow down on the addition of anymore fish. The ich was a warning sign, take heed. Slow down, read as much as you can (the club has a great library, and librarian for that matter) wwm (wet web media) is a very resourceful website, and form a directional plan and stick to it (either fish only, or a FEW small fish and corals).
Most of all, Please think of the animals that are your responsibility and require your care.
