White Spot Outbreak

I have a white spot outbreak  I think I caught it reasonably early and a lot of fish are showing no symptoms with some showing just a few spots. However two or three Rummy nose tetra's look on the way out, they keep doing floating head stands and drifting before seeming to recover for a while and then floating around before seeming to recover again. I have treated the tank and if I understand the White spot life cycle there should be no further infection as the little sods will be killed when they start swimming.

Should I remove them? I have no quarantine tank or should I leave them and hope they recover?

Also, after treatment should I get some carbon to remove the meds or just let normal water changes sort it?

Thanks Sue. Not keen on doing big water changes, how about lots of small ones and carbon? 

Well they all made it  Day 7 today which according to the med instructions is the final day and if all clear carbon can be added. None of the Rummie's are floating or doing headstands anymore and all clear of spots, same for the Harley's. I am still a little concerned as a couple of Cardinals have a few spots but they look like old marks rather than new spots and seem healthy. Basically the treatment, (Interpet Anti White Spot) says to dose on day 1, then repeat on day 4. Should be cleared by day 7 but can be repeated if necessary. Should I

A) Water change and add carbon
B) Add another 4 day dose of med
C) Neither, wait and see

Although white spot is a disease that people worry about, it's actually one where the treatment usually seems to succeed. I've only had to treat for it once, with some fish I inherited with a second hand tank. I didn't turn the temperature up, didn't do large water changes or use carbon afterwards, the disease went away and I had no subsequent problems, snails and an amano shrimp were unaffected.

I'd not stop the treatment too early, there is always the chance of a comeback if you do, better safe than sorry.

It's the internal diseases that are more problematic.
