QT with copper?

I generally use a UV sterilizer during QT. TMZ, have you ever used one with the tank transfer method? What do you do to clean your equipment before introducing it into the next tank.

I also typically use pre-seeded filter media in the HOB filter to minimize the cycle during QT. Won't any treatment such as prazipro, or copper kill off the beneficial bacteria colony on this media and render it useless?

Since Christmas is upon us I will likely not have another opportunity to visit these forums until the day I am to pick up the new fish so I think for this time I will use the following procedure to QT. I'll have three days to consider changes to it before the first transfer.

I'll begin with the 12 day transfer method with UV, heater and PVC in the tank. The transfer will occur with only a second, pre-sterilized heater in the tank, maybe an air stone. I'll run chlorinated water through the UV and pump in a bucket with the heater and pvc for 30 mins to sterilize, then use two or three 30 min rinse cycles in fresh water with dechlor to eliminate the chlorine before I move the UV to the new tank. The heater and pvc will be allowed to thoroughly dry with the first tank until it's time to set them up for the next transfer. At the fifth and final transfer I'll introduce the HOB, with pre-seeded filter media for the duration of the QT, 2 weeks. I will avoid medicating the QT unless signs of a parasite are detected. If I begin medication then the QT period will be extended until the fish is healthy.

I may consider doing a formalin or freshwater dip at each transfer as well.

This method really won't accelerate my typical 4 to 6 week QT much but should be more effective at eliminating ich and provide enough opportunity to detect other parasites before introducing the new fish to my system.

No, I haven't.;decided drying it out for reach transfer was too much trouble. I use a KISS(keep it simple stupid) method on transfer tanks ; it suits me.

What do you do to clean your equipment before introducing it into the next tank.

I just rinse it with tap water ;towel it off and lay it out to dry. Ich dies when dried even the cysts.

If I use preseeded sponge or granulated activated carbon , I toss it as a tank is vacated. I don't use these anymore though since ammonia hasn't been an issue. I do add a prescribed amount of detoxifier( AmmoLock is what I have on hand) on the second day just in case.

No it won't.

Copper sulfate a free copper med will depress it about 20% but it will adjust. Bound copper meds like cupramine and coppersafe will suppress it less.

Prazi pro shouldn't ham it form what I've read and experienced.

Good Luck and Merry Christmas.
 
I have used the tank transfer method very effectively. With a small fish I have not worried about a biofilter...I use Amquel for 3 days. I use barebottom with a strong airstone....very low tech. As soon as I transfer the fish, I pour a good amount of bleach into the tank (I think I read this in a book by Martin Moe) I let the bleach sit for a day. Then I thoroughly rinse the tank, airstone, and any PVC I might have in there...clean well untill you can no longer smell the chlorine. I immediately set the tank up with new salt water to give it time to age before the next transfer. I have had GREAT success with angels and butterflies with this method.
 
TMZ-thanks for the bio lesson. I never knew the hypotonic / hypertonic relationship with saltwater and freshwater fish. It now makes sense why you can drop s.g. rapidly, but need to slowly raise it. Thanks again!
 
Regarding,intestininal flora suppression in tangs, I don't recall if that is backed up by a study and may just be just specualation on what might happen. Would like to read up on it again though if you have a reference. I used copper sulfate ,then switched to cupramine for awhile but like th transfer process much better .

Here's an article on the classification of one of the (huge!) bacterial symbionts. There are associated references, but I have not found a report on copper. I think it's more than anecdotal evidence. I just can't find it! :spin3:

My system has about 490 very healty fishin

Sorry it was late when I posted this. I only have about 40 fish .

Thanks for the link. As you note it does not speak to any effect copper may have on the . Epulopiscium or other symbionts. I'll look around again to see if there is something conclusive.I've looked before but that wasa while ago.

I'm skeptical because there are a few questions that need answers before extrapolating the existence of a particular symbiont to a conclusion that copper treatment as performed in qt tanks suppresses it.
Cu ,free copper attacks the parasite in open water. Would free copper make it all the way into the gut of a fish in inorganic toxic form . Copper binds to organics many of which are refractory( hard to break down) in a reef tank or the ocean . ,If it didn't all our tanks would be loaded with deadly free copper from salt mix, supplements, foods , etc. It is free copper that is toxic.
Lots of copper is already being digestedin the fish gut from foods as it is.

If so would it damage the symbionts? Many bacteria metabolize metals.

Anecdotally,FWIW I have 5 tangs, I've had several of them for 7 yrs +. 4 were treated with copper at one time or another.
