Thanks to the great advice from this forum I have been able to maintain a crystal clear pool. I did have a question involving running water features (beach entrance bubblers, water sheers), spa jets ect. How often do you guys run your water features (days a week and length of time)to make sure water does not get to stagnant in them. I mainly ask because I don't want any issues with algae. Also in our beach entrance we have 2 umbrella sleeves. Do you guys leave the covers on them or keep them open to make sure you get more water circulation. Thanks again for everything!
