When your water goes from much to crystal clear. This thing is a miracle and took my new 75 gallon tank from heartbreak to crystal clear in a few days.
My water is crystal clear now If I have no timer how often should I turn on machine

UVC bulbs typically last about 6-9 months in constant use. Some bulbs can last up to a year. To lengthen the service of your bulb, we suggest once your water is sparkling clear for 7 full days, start using your UV on a limited as needed basis. Run it with your light timer or only on weekends, etc.
Does it kill parasites like Ich?

This sterilizer does not kill parasites.
After I do a partial change, I add good bacteria. How long should I keep the sterilizer turned off?

There are times that you do not want to operate your Green Killing Machine 24/7. We would recommend turning the GKM off for 1 week to allow the added good bacteria to grow on the bio filters. After that, use the GKM as needed to maintain desired water clarity.
