The masons just finished installing the bull nose coping stones around the pool. There is a fair amount of concrete mortar which has fallen into the pool during the process. My pump & filter is ready to be started but I need some advice. My DE filter was backwashed by the PB during the closing last fall. I was planning on doing a thorough cleaning of the filter prior to opening but am now considering waiting to do that until after I suck up all of the concrete which has fallen into the pool.
1. Should I pump to waste during the startup and try to get rid of some of the concrete mess?
2. Can the concrete damage my DE filter, pump or piping?
3. Should I add some DE to my filter now and then take it apart for a thorough cleaning after the concrete mess is out of the pool?
Thanks in advance for your help.
