The cons of quarantine

[howdy20012002]

I totally agree that having a separate system will allow the fish to acclimatize to the situation a lot better and will definitely help the fish make the transistion.
I am not trying to disrespect you or say that your idea doesn't have merit in that sense of acclimatizing.
what I am saying is that it will not help save your system if the fish has marine velvet or ich.
if anything, I would shut the second tank off from the main system before you add the fish and leave it shut off for the the quarantine process.
also, if the fish died during the process, make sure you just don't open the flood gates open again and bring it back into the main system until you leave it fishless for a least 6 weeks..just to make sure that if it was a parasite that killed the fish, it is not just waiting for the chance to link up with your fish in your main display.

I am speaking from experience and alot of reading.
I personally have 6 quarantine systems with over a 1000 gallons of water up and running.

According to online sources, the symptoms you notice are typically the last stages of the process.
the parasite is swimming around in your system long before you notice it unless of course you buy a fish already completely covered in the parasite.

I totally agree btw about being careful with copper..it is a very handy tool but make sure that you stay on top of it...it can kill the fish just as easily as the disease you are trying to eradicate

on another note, for those individuals that think you can't have ich free systems, I would have to disagree with you 100 percent.
i currently have the ich magnet powder blues and browns, and multiple other tangs that are not showing a single spot after their quarantining and have been placed in the main system...it is possible, but only through a proper quarantining process..

I personally am having a struggle because I don't know if I want to say the hell with it and treat all incoming fish with copper for a min 2 weeks during quarantine.
that is the only true way that I know the fish will be parasite free before adding it to my main system...
hyposalinity will work for ich, but not for marine velvet and it should be done for at a least a month...It is not financially feasible for me to quarantine fish for a month.
