    How long between testing at start up?

    Just got the cover off and replaced about a third of the pool volume overnight. Got the filter running with new sand. How long should I let the water circulate before taking my first set of tests and then how long in between adding whatever is needed before the next tests? I am thinking one turn over but do not know how long that is? Is a couple hours sufficient? Water is crystal clear with some dirt/sand on the bottom.

    Hi, Dave,

    Yeah, an hour is probably all you need to stir things up.....two hours is gracious plenty.

    The very first time you open in the spring, I would run the pump for several hours before testing. The water can form layers with different temperature and salinity over the winter, and if that happens, it can sometimes take a little extra time to mix everything back up. After that, one hour is fine.
