    I've been usng a lot of the solids from the swirl filter to feed a couple of worm farms and was toying with the idea of a F&D gravel gb that has a lot of compost worms and gets straight solids from the swirl filter. Could be used to help if your pushing the limit on fish or using floating rafts etc. The gb would need its own sump.
