The solution to this is passing your water through a UV and/or Ozonation filter. However, this only cleans out the water passing through your system, not necessarily the water traveling to each plant. However, if you have a unique water return for each plant or just a few, you would be much better off. This is the same problem I've run into with doing an ebb/flow system, because it is just so easy to pass along virus/bacteria/fungus plant to plant, especially from the roots.
