I have a Lifeguard UV Sterilizer for my 75 gallon tank that I want to use. I lost the instruction booklet, and now, naturally, I have a few questions. Looking at the sterilizer, with the label facing me, which is the input side of the sterilizer, the left or right port? Wouldn't seem to make a difference, but the thought did occur to me, and I couldn't answer the question. Also, is there a specific time ( both time length and time period) that would be best to run the sterilizer? At night, during the day, for how long? I 'm using it as more a preventative measure against GWA than anything else. Thx in advance.
