I run my pump in a flood and drain set up 8 times a day for 15 minutes. I have used both rock wool cubes and red clay pellets, both work equally well. My aeroponic pump runs 24/7. I also put 1 tablespoon of hydrogen peroxide per gallon of water.
sharprubberduck.com is an excellent site, take a look, it really helped me out .
