hi all,
i have a aqua flow 3 800lh internal filter on my 100l tank. placed so it is flowing across the length of the tank. i have it on the lowest flow. (gouramis) media is black carbon impreg sponge at bottom and white filter floss at top.
i do a 20-30% water change weekly and sand vac.
by the next day the sand is covered in poo and doesn't seem to be getting sucked into filter. iv been watching it and the flow goes round the tank and the dirt seems to be pulled back up (not through filter) and blows back round the tank?!
not sure if this makes any difference but the sand under the filter has a dip in it like its blowing out of the bottom too?
have i done something wrong?
thanks. xx
