Seen few videos of planted tanks with no filter or water changes.
I've watched a few videos on YT with titles such as this:
No Filter, No CO2, No Ferts, No Water Changes - 5 Gallon Nano Dirted Tank.
Can somebody explain to me how that works? Do the plants get rid of things like ammonia and nitrates from the water? What happens to fish poo?
Why do people get so worried about their filters if their plants help anyway?
Does it only work with a lot of plants?
Any information on that subject would interest me.
