BF McUmber Posted May 20, 2021 Share Posted May 20, 2021 I have a tidal 35 hob filter. When you pull the media basket out , the water flows through the sponges backwards, effectively back washing the filter media to some extent. What comes out is a lot of algae, plant detritus, and probably some fish poop. This water does not really have any positive value to the filter and can/ should be removed, correct? I mainly want to confirm my understanding. That the bacteria in the sponge is the most important thing so not touching the sponge as often could be good. Then by back washing it could just make it not clog as quickly with detritus which also could be good. Thank you Link to comment Share on other sites More sharing options...
