Of course you're going to get a biological growth. This, and most others are not made for raw well water without continuous chlorination like with municipal waters especially where a phosphate is used for scale removal that is a nutrient. Don't blame the product that is perfectly fine, but your lack of water treatment knowledge and incorrect application. Â

I just got this filter in January 2013 and so for it is really doing the job I need for it to do because I have really hard water, I live in the country. I am really glad I added it to my water line and I recommend every get one when they get a ice machine.
This item is a excellent item to be used as a ice machines in line filter. The filter is easy to install and appears easy to replace without any problems. We have not replaced the filter as of yet, because you have to change the filter every six months.
