You can run it all the time that you are not using the pool If you want too. It really depends on your environment surrounding your pool. If your pool is gunite then you need to be careful on a new surface using a cleaner until the plaster cures. Ask you builder when it is safe to use your cleaner...

Hope this helps Rusty
