@Susan Bates as I suspect you are finding out the hard way, Cryptocaryon irritans (Marine whitespot) is a difficult parasite to deal with.
From my understanding there are probably only two ways to totally eradicate it - exposure to copper (at the correct level and at the correct time of it's life cycle) and breaking it's life cycle by preventing access to a host.
Neither of these ways can be undertaken in a display tank without access to a second hospital tank.
A bit of a generalisation, but no product can eliminate Cryptocaryon irritans and at the same time cause no problems for your corals, inverts etc. - that product does not exist - there is no magic bullet to this problem.
If you read the wording for these products, they do not claim to eradicate Cryptocaryon -
Vertonex - To assist in the treatment of white spot (cryptocaryon irritans) when corals and invertebrates are present in marine aquaria.
Polyp Lab Medic - It contains an antibiotic component and a reef-safe oxidizing agent that work together to help eliminate parasites.
What exactly does 'assist' and 'help' actually mean??
So that they are not harmful to corals, inverts etc you will find that the active ingredient is watered down to such an extent that it will have limited success against the actual parasite. Now, I'm not saying that they don't 'help' as they may manage to kill off some of the parasites and thus give the fish a chance to build up it's immunity, but they won't eliminate it. If a stress event re-occours then it is likely that you will again see white spot on your fish.
thanks, what about the UV light i was told to buy this it would help@Susan Bates as I suspect you are finding out the hard way, Cryptocaryon irritans (Marine whitespot) is a difficult parasite to deal with.
