so as title says i need a very good filter for my 1 ft tank so far only has a hang on filter which does not suck in the bn poop and tank gets very dirty i was thinking on getting and undergravel filter even though my tank has no gravel any suggestion on other filter or will undergravel filter suck in the small bn
my tank currently has 9 bn altogether 2 are about 7cm other 9 are only 3cm and 1 cherry shrimp which im not sure if still alive
