I have a Hayward EC40 DE filter. During start up of the pump, I get a large white cloud of what I think is my DE. The pump and filter is only 1 year old and I store it in my basement during the winter. I just replaced the liner in the pool last week and filled it with 13000 gallons of city water. I am good on my ph and chlorine. What should I be checking?
