Believe me, I washed that gravel as much as I could - for hours, wasting huge amounts of water. But after letting a new system run without fish or plants for about a week, the sump tank if pretty full of dust leftover from the media, and the FT has some too.
How do I clear this out? Can I just put a sock over the pipes and stir it, or is there a better way? I plan on building a radial flow filter "soon"©, would that help with the dust, should I build it now?
Any tips much appreciated, I want sparkling water before I introduce the fish
