Help with ICK

Wifes not thriled about another tank,Ive got way to much money in this one but we all are getting an incredible amount of enjoyment out of it.One thing that is confusing me is this morning for example the fish were covered with the white dust looking stuff and there color was very faded (DONINO DAMSEL}to a light gray and there resperation was fast and labored, this evening they look like different fish,much better not cured but better.O Happy Thanksgiving
 
Cryptocaryon's life cycle can lead to a false sense of security among aquarists. The white spots can often seem to disappear on their own. However, this does not mean that the ich is gone, rather the parasite is simply in a different part of its life cycle either incubating in the substrate or as a free floating tomite. When it reattaches to the fish weeks later after multiplying, then the white spots return with a greater vengeance.

Copper and hyposalinity are the ONLY scientifically proven ways of killing crytopcaryon. The only way to properly do this is in a simple Q-tank.

I fought an epic 2.5 month battle with crypto on my hippo tang. Fortunately, it was in quarantine. This likely saved everything else in my display tank.
 
And there you go... I repeat, proper use of the quarantine tank is essential to long term success in this hobby. The alternative is at best Russian roulette, and at worst simple stupidity. That's why my first rule of marine aquariums is always have two of them.
