I can see that the pores clogging up with build up. so I will get a defuser. I know my water does not mix because we swim in it and it is warm on top and go down about 10 to 12 feet and it is very cold. so when do I need to turn it over and do I run pump short periods when I start making it a little longer each day. do I have to run pump all the time? and do I just worry about summer months
