Yeah guys..... I've been running my system for a few months and noticed something after switching to tygon tube. After about a month of running the tube started to get a white film on the inside. I took the equipment out this weekend and flushed it with about 5 gallons of distilled water. I would fill the system up and add about 3 tablespoons of rubbing alcohol to try and clean it up with no success. I did this about ten times and then flushed it out another 10 times with just distilled water. Needless to say the tube still has the film.
I added some antifreeze just to bring the color to green so the film doesn't show as much but it still bothers me that 25.00 worth of tygon is "dirty".
Anyone know what this is caused from??? Or better yet how to avoid it??
