Hey guys - I have an in-ground 15,000 gallon pool that was just finished last week. Today my PB came out and hooked up the vacuum and showed me how to run the equipment.
So, this evening I tested the water and the TA was slightly low so I added some baking soda (per the BBB method) and just out of curiosity, I stuck my hand in to make sure the returns were on. So this brings me to my question, if the pump is on, and the spa spillover and the vacuum are doing their thing, do the returns need to be going in order to get proper circulation for the chemicals? I know before the PB hooked up the vacuum, the returns were blowing like crazy. I have a 4 speed pump and the PB turned the pump on a lower setting to save electricity (which is good) so do I need to adjust the speed to get the returns flowing like they were before? Or is it normal to get not much out of the returns if the spillover is on and the vacuum is on?
