I ended up not changing much. Although it was a cheap and nasty all in one I quite liked the filter setup. Simple powerhead to spraybar with the water landing in a plastic box with holes on the bottom, giving a rainfall effect. I removed the floss when it died and left the coarse sponge below the grill. (Excuse the Rooibos teabag 
). I know some would say I need more media but I have always had minimilist tendencies, and that frogbit covers 100% of the surface.
If I add a normal sponge filter to the inlet the flow is reduced to a trickle. This would have worked as my original plan was to use this as a breeding / fry tank. Now its a QT and home to 13 adult nano fish that makes the flow inadequate. Not a problem the flow is fine without an inlet filter. Then I decided I may try this as a species tank. I know technically its probably too small but as a QT its working well and the fish behaviour is good, as is the water quality. But then what happens if / when they breed. And they will with nothing else in the tank, and in time I may add shrimp. So I needed an inlet filter without reducing the flow.
This did the trick
Hang on a minute... Now I have a perfectly good nano powerhead and filter just lying around. Does anyone have a small glass box lying around so I can have somewhere to store them?
