Largest tank you've successfully run with a single FX5?

I also have a love hat relationship with duckweed. Helps so much with water quality. Also gets everywhere. I have to keep african cichlids just to eat the excess.

When living in the US, I also used duckweed to great advantage, It ate nitrate like sponge, but I had to shovel it out of some sumps daily to the compost eeap, even though my C, bocourti loved it, and any other green that hit the tank
.


Here in Panama Salvinia water and lettuce work as nitrate sucking substitute, and also help filter the sun on the surface of the sump, that gets about 6 hours of direct morning sunlight.
But just like duckweed, handfuls of it, and water lettuce have to be pulled out almost daily, for export of nitrate.

I've moved to mostly sponge filters and plants for filtering. Water is more consistent with fewer water changes. Canisters and hang on backs mostly for polishing now.
