michael.qian Posted November 23, 2007 Report Share Posted November 23, 2007 Hi all So far I have cleaned my Fluval 405 filter twice. Each time after reassembling and restarting, the filter sends out loads of dirty debris into my tank, but this doesn't last long though only about 30 seconds and the debris gets filtered away again. Just wondering if this is normal or harmful? Cheers Quote Link to comment Share on other sites More sharing options...

michael.qian Posted November 24, 2007 Author Report Share Posted November 24, 2007 I think it's because after cleaning the interior of the filter there's lots of debris loose and floating around, so when water gets pumped up the debris comes up with the water.

henward Posted November 24, 2007 Report Share Posted November 24, 2007 i have a semi scientific explanation the debris comes from the tubes of your inlet and outlet pipes. these are strands of algae and organisms that are used to the certain flow of your filter. when you reverse that the sructure of the organism isnt deisgned to withstand the opposite flow because its spent its whole life trying to withstand the normal day to day flow, they dislodge and whallaaa you have debris but yeah harmless:D im am such a geek im sorry....
