Just set up a new 40 gallon breeder for a quarantine tank. Trying to decide if I should plumb it to the 20 gallon long below for a sump or not. Do most people run skimmers or sumps for their quarantine tanks?

Dcmartinpc, Do you use any type of copper treatment? Just trying to figure out what meds I will be needing for my first time using a quarantine.
Observe for 6 weeks, no prophylactic treatment. Isn't adding a dozen fish at the same time, to either a 40 gal qt or main tank going to be way too much for the bacteria load to handle. From my understanding, that is going to be a recipe for adding stress right off the bat and probably really mess with ammonia etc. Since I got burned by MV, now that I can add fish, I'm only adding 2-3 fish at a time and a good 4-6 weeks apart. I have 3 fish in observation now at the 2 week mark. All doing great. Haven't decided if I'm going to do any medications or just get them nice and fat and healthy. I had to add two mandarins to the DT without going through QT as I lost the 2 I first tried in the QT tank. Right in with the pods and both doing well so far as I can tell.
Really rethink how many fish you're going to add to the QT tank to begin with. no more than 4 I'd think
+1 to above, adding 12 fish at once is a recipe for disaster. It will overwhelm your biofilter. 1-2 at a time is going to be your safest bet. Not to mention, if you quarantine 12 fish at once, and one has velvet, there is a good chance you will lose all 12.
I keep a 20 gal quarantine set up, cycled with LR and sand and a small CUC (and a couple peppermint shrimp, there were aiptaisia on the LR). Right now it's fallow because the last inhabitant had velvetObserve for 6 weeks, no prophylactic treatment.
A drawback to this is that the fish have to be observed very closely and the aquarist has to know what to look for - which I don't, always. I lost my last two fish to velvet a week into quarantine. I think I could have caught it in in time to treat the first if I had recognized it better (I don't think I could have done anything about the second - poor guy went from healthy and eating to dead in about 6 hours).
The drawback to prophylactic treatment (as I see it) is that every drug has some negative effect and used improperly, can do more harm than good. Plenty of people kill fish with copper, it seems. I nursed a wrasse through flukes and a bacterial infection only to overdose it with an unnecessary follow up treatment of prazi-pro. It's up to the individual to weigh the pros and cons based on their own comfort level and lifestyle.
