Hyoithetically, what if...
So, I am looking to add some fish, but my only options are Petco/Petsmart, so I figured that I better have a quarantine tank. Since all my filters run on Aquaclear substrate, which has foam blocks, I figured that I could have a only temporarily filled aquarium, with the filter substrate living in a different filter during the time when I am not acclimating/fixing fish (This also serves to make my parents less mad, with two tanks already).
However, my only option right now is a three gallon bucket (again, the Parents Against Tanks front), and that is not conducive to a filter. So my question is, would it work for me just to put the filter foam in the tank with the sick fish, and not bother with the filter? Would that work if I did lots of partial water changes?
Also, if this works, this will make my father happy, who already feels that I use too many plugs. He calls my room The Power Plant.
Sometimes, you just have to buy a fish.
Sometimes, you really shouldn't
