Just a quick question. Currently on low speed my spa does not fill with any water, therefore it seems on low speed my spa is not circulating any pool water into it. I would think I would want the water circulating through both so I don't have issues with the spa. I don't want to run on high-speed all day as the aeration will only add to the pH rising I am trying to keep level (new pool). Thoughts?
What do you guys recommend?
