Well, the water finally reached the middle of the skimmer today. 46 hours! I didn't get to talk with the pool installers before they left the other day so I don't know if the filter is ready to be turned on. DE added, etc. They also didn't leave the manual for the pump and filter so I haven't a clue as to what to do first. I have a call out to them, but was wondering how long is it ok to leave the water sit without filtering and adding initial chemicals? Water temp is only 58.
