Boomboy's Comeback Tank

[lastlight]

I also run my TLF reactors with the sponge like that. I like a gap where I can easily monitor what is making it past the sponge when bringing new media online. I run the output into my filter sock until that column of water above the plate is clear and then I know I'm good. The sponge above the plate makes that tougher to see. Silly reason maybe but just sayin'...
