Blue, I noticed you are using bleach to clean your stuff. Bleach does an OK job but leaves residue behind and will not kill all pathogens. I would recommend you use H2o2 for cleaning. H2o2 does cost more than bleach but does a better job. Here is some info on cleaning using H2o2. I use it for everything when cleaning.
Sterilizing
Hydrogen peroxide (H2O2) is by far the most practical product to use for sterilizing aggregate media. Unlike system parts with smooth surfaces, media such as hydroton are designed with irregular surfaces and small pores meant to capture & store nutrient solution. As a result, bleach can be flushed from smooth system parts with one fresh-water rinse, but media requires several flushes before chlorine levels in the remaining solution become safe enough for plants. This is not a concern with H2O2 as one flush is enough to return media to a safe condition. And unlike bleach, because the weak H2O2 solution will naturally breakdown to a harmless condition when exposed to air for several hours, no rinsing is required if you don't need to replant right away.
Because it is the least expensive, bleach may be more practical to use for the rest of your system. However, many find that the small savings doesn't outweigh the convenience of sterilizing both the system & media together at the same time and flushing only once, or not at all depending on the urgency to replant.
To sterilize with H2O2, you can use the same 5 gallon bucket that was used to clean the media. Fill it with 4 gallons of water, then add 2 cups (16 oz) of the common drug store variety hydrogen peroxide, this is typically a 3% solution (check the label). For other strengths use a scaled down quantity. For example, if using a 30% strength use only 1/10 or 1.6 oz.
Place the container (with the media inside) into the H2O2 solution. After standing in the solution for 1 hour, remove it and let it drain back into the bucket. Rinse if needed, then repeat with the next container of media.
See the H2O2 page for more.
