On my filter the fluval 404 it seems to not be sucking up debris as well??? I have not cleaned it yet does anyone have experience cleaning this model??
When was the last maintenance done on it? And is it a planted tank? My XP's have to be cleaned every 3 weeks due to small plant matter clogging the sponges.
Like almost every filter, your are suppose to do regular metainances. Disconnet the filter and take it apart and clean the filter basket and everything inside it ... caution not to use chlroinated water for obvious reasons.
I agree, disconnect it, open it up, rinse the sponges in old tank water, rinse the filter compartment out, and rinse any media in old tank water, and reconnect.
