SA>He has designed in quite a few places where the water doesn't flow,

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>Is this practical? I assume that even one spore would grow into a

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