I soaked over night in water and soap the hosed off. put filter together again and started filter added De ran filter. The filter runs good for about 1 hour before the discharge is weak. I pump the handel drain from the bottom of the filter and re start. before i keep doing this process I would like some help. I have not added more de to the filter except for the initial start up. the kids are killing me and what to swim.thanks in advance for any help.
