Ok, so I got new sponges and ceramic rings for my FX5, and after an uber cleaning I put some fresh black substrate in (which will look pretty slick with an Albino Oscar and a Green Phantom pleco running around IMO 
) anyhow, I took the well established sponge filter out of my female betta tank and squeezed all the yum yums out of it near the intake of the FX5 and Im letting it run in there for the night. I also pulled a pretty dicently sized peace of DW, about 2 cups worth of gravel, a few plants and a plastic petsmart cave from the same tank and put it all in the 75. How long do you guys think it would take for BB to take hold?
