Just set this pool up and ran the SWG for 5 hours last night to get things rolling. PH and Chlorine are within range, and the water is clear. Here's my question as I'm a noob to these SWG's. I have always ran my filters with a little added D.E. through the skimmer as I always felt it made the water "look better" for the lack of a better term. Can I still add the D.E. to the filter, via the skimmer with the SWG? Thanks for the anticipated replies. BTW, great forum, great people. Howie
