I decided to order the 8gallon Liquidator. I have one question about where to connect it to the suction side. Since I have a spa, I could connect it to the pool suction line or the suction line right before it goes into the pump so that regardless of whether I am in pool mode or in spa mode chlorine is injected. I guess my concern is that if I am in spa mode and it is connected on the combined line that I may be putting too much chlorine in. Thoughts?
