100mg/hr into 1500l is .067mg/l hr, or about 1/15th what the rule of thumb calls for. Of course, that rule assumes that you'll reach your ORP target of about 350mv, and the controller will then switch off the O3. As I said before, I'm no expert on these systems. But from what I've read, I think it's unlikely you'll reach dangerous levels with the Hailea. However, an ORP meter will let you see if the ozone is making any difference, and it's a is a great tool for understanding your water quality anyway.
