Sick fish....QT tanks and the headaches... how do you cope?

Maybe u have some parasite or bacteria in ur tanks water, maybe try a uv sterilizer. Just an idea. I know it helped out in my tank.

I think a quarantine tank is a MUST for all large tanks simply because of the number of lives invested (and often the number of dollars) in the tank. One new fish can wipe out the whole tank. Marine Velvet is probably the scariest SW disease.

Copper is the devil imo. I won't buy it. Copper doesn't treat anything that a different (safer and better) medication could treat. For Velvet and Brookynella I use Formalin (dips) which is easier to use and is safer for the fish.

Personally, I dip all incoming fish in FW (RO/DI) with some methylene blue after they are done drop acclimating (to the quarantine tank). You NEED a digital pH meter for this as you have to match the pH of the freshwater with the pH of the quarantine tank. It takes a tiny, tiny, tiny amount of baking soda to raise the pH of RO water. Here's a great reference: http://www.reefland.com/forum/marine...ne-fishes.html. This same author also has a great reference for Formalin dips, although I don't think that all incoming Clowns should be dipped as most are captive bred these days and tougher...if they are wild caught, then yes they should be dipped. http://www.reefland.com/forum/marine...ne-fishes.html

Here's something I typed out for someone else (I'm feeling lazy):

Use at least 50% water from an established tank to fill the QT, and add a seasoned filter pad from the established tank as well. I like to use a SeaChem Ammonia Alert which works very well and lasts a year. I use AmQuel to detoxify ammonia when needed. Most ammonia test kits are not compatible with ammonia detoxifiers, but the Ammonia Alert is. You don't need a light on it, but you should have a lid of some sort because new and sick fish startle easily and are prone to jumping out.

For hyposalinity you HAVE TO use a refractometer to measure salinity as you need to be very accurate. Here is an ok link the hypo...wish I could find a better one: http://www.aquariacentral.com/forums...o-Hyposalinity

Well I hate to say it but I would be leaning more towards Velvet then anything else as its a fast killer, it wiped out my very first 65 gal in a matter of days after it had been up for almost 6 months, I only had one survivor a yellow tang. I really don't know where it came from or how to treat for it, if you even can because it kills so fast.

I don't have a QT set-up full time but can put one together in a matter of minutes. I usually only buy fish from a few LFS & from well established tanks.

A UV will do nothing for Velvet, has one on my 65 to no avale. All my fish would eat until the last day or 2, all of them had a very slimy coat & where very pale. My Volitan Lion was the hardest one to watch go because of the way Velvet eat away at it huge fins, desolved them right to the cartilage. It was so very hard to watch.

Good luck mate, hope I am very wrong for the rest of your fishes sake.
