ok so i convinced my aunt to get an fx5 for her tank. she mainly has small cichlids like electric blues and what not. i keep up with the water changes and what not for her, and now it was time to clean the filter. inside the filter it has those sponges around the rims of the tray. when i went to clean it this time around the sponges were like a dark pink, they used to be white i think.
what the crap happend? normal? safe?
thanks
