Hi Everyone. Just bought myself a little aquaone tank to set up a betta/shrimp tank. Its got an undergravel filter (I know, they're not very good but decided to try it anyway.) My question is: The 'powerhead' on the filer fits just above the plastic underground bit. Does anyone know whether a space is needed between the powerhead and the gravel or is it ok to have the gravel up to the bottom of the powerhead?? Reading that back to myself I'm just hoping someone knows just what the hell I mean!
