If you DO NOT use your filter and don't cycle the tank, you will have to do 100% water changes (quite laborious in a 5 gallon).
Does cycling apply to all filter styles, or only the biological sponge type filters? This filtration system uses two removable media filters that according to the directions get replaced once a month.
From what I have read the biological filters are better, but since Dory is already in her new home, I am unsure about how we would cycle one and have it remain safe for her.
Last question (for now haha!) If we want to add to her home (more plants, new hiding places), is it best to wait until we do a water change, or can we carefully add things while she is swimming around?
