SA>Thank you for taking the time to help me with understanding my
SA>experiment.  It's nice to have help from an expert.

SA>>I think the above experiment does not give fully demonstrate your thoery
SA>>as your boss' idea is to have a flowing system so if you design your
SA>>system to eliminate the accumulation of stagnant water you should have low
SA>>risk of microorganism growth.

SA>He has designed in quite a few places where the water doesn't flow,
SA>plus the system may be turned off for many months at a time.  I will
SA>set up another experiment with a small teflon pump and see if it makes
SA>a difference.

SA>>As your experiment have stagnant water for a month,  I am not surprised
SA>>that that you have fungus growth ( I don't think it is bacteia as you
SA>>probably need a microscope to see bacterial threads).

SA>Fungus! That never occured to me.  I was thinking that the threads
SA>were collections of many bacteria, not individual bacteria that are
SA>big enough to see.  Maybe I should order a microscope (not that I
SA>would understand what I was seeing)...

SA>>Also another way to eliminate fungus growth is to have a good Quality
SA>>Assurance so to make sure that you eliminate the chances of spore 
SA>>contaminaton of the deionised water being fed into the system.  (Some sort
SA>>of closed system migt be in order from your deioniser to your tanks)

SA>Is this practical? I assume that even one spore would grow into a
SA>thriving colony.  Is it possible to eliminate every single spore? 


Could you heat the water to near boiling every now and then to kill the
stuff off?
