Out of curiosity, what sort of water changes do you think it would take?
I'm a long-time proponent of filterless planted tanks. I think they have
more up sides then down sides. As in all things you have to weigh your needs
and make decisions to fit your circumstances.
First off, "filterless" doesn't mean without circulation and it doesn't mean
without water changes. CIrculation is important in any tank. And I would
never try maintaining a tank without water changes. Some people would.
The key ingredients that make unfiltered plant tanks safe for fish --
especially for delicate fish -- are a lot of healthy plants and rapid plant
growth. The tank must have enough plant growth so that the nutrient content
of the plants and cuttings you remove (along with water changes) balance the
nutrient content of the food and fertilizers that you add. That usually
means bright light, CO2 and a moderate to low fish load.
I've never kept discus, much less in an unfiltered tank. I may never keep
discus. and I'm even less likely to keep discus in an unfiltered tank. It
might be perfectly safe for the fish, but I don't see much sense in gambling
with the well-being of such expensive livestock. In the case of discus,
healthy, good quality fish may cost quite a bit more than the filter you
would need to help ensure their good health.
