1) I have a new tank and am wanting to set up a QT
also for my new fish. Since there is not going to be a constant population of fish in the QT
(fish only in it for a few weeks after purchasing them), can I use an external hang-on type filter with activated carbon and zeolite for filtration instead of a full on wet-dry with biological filters, etc.?? It seems pointless to have another full system with LR
and all the other stuff for a QT
that only has fish in it for a limited time.
Also, how long should I leave fish in the QT
2) After cycling the new tank with shrimp and assuming the bacteria population at that point is fairly high, what type of fish load should I introduce to the tank initally? I would think that I could put in a number of fish based on what the bacteria population should be. I would also assume that I would want to put in the less aggresive fish first to get them established before introducing the more aggressive ones.
Sorry for the long question!!
