	How to:	Here I am starting to wash 500 cups with a 10 percent bleach solution. I think I will add a dishwasher to the things I need to buy.
	How To:	I let the grow rocks soak in the same bleach solution overnight and then rinse them with clean water in a bucket with holes drilled in the bottom.
	How To:	For the larger systems I plug up the intake to the system and fill the cups with water and then pour a little bleach in each cup. Let soak overnight to loosen the crud.
