I am looking to set up a qt tank incase of emegency. I am using an hob filter on my 20gal long and dont not want to add a sponge filter. I would like to add a second hob filter on my 20 gal long and be able to pull it off and put it on the qt tank. The only problem is every hob filter I see has active carbon which would just filter out the meds I would add if they where needed. I hope I never have to use this tank for the medicating purpose but I just want to be on the safe sidem and be prepared. does anyone know of a hob filter that does not have an active carbon filter, or if the active carbon filter can be removed and replaced with a sponge of some sort
