but that does not seem possible with no biological filtration.
, the only time you may
be without biological filtration in your Q-tank is if you are medicating and the meds crash your filter. If you have a small HOB
filter like a biowheel, or a sponge filter they can be run on the main tank when the Q-tank is not set up and you only need move it over when you set up the q-tank. If you are doing a completely filterless q-tank, you need to be doing daily 50% water changes and that may not keep up with it for long.
