Do I apply eclipse 3 DIRECTLY to pool filter or bypass the filter first . , than filter pool ?
I can not find Emerge shock to use with my Eclipse3. No one in my area sells Eclipse 3 as my dealer retired. Could your give me the name of a shock product that is safe to use with Eclipse 3?
Thank You Very Much
