Reef Tank - I can't win

[Antrias]

Thank guys for the advice I'll try not to freak out. I've just had bad experiences with ich however could be from my over acting to correct the breakouts. Should I not do another water change for a little while? Should I feed twice a day for a while?

As for the clam - A tang knocked it over one day but I didn't think much of it - that probably is what did it - tore it's foot.
