I tore down my DE filter yesterday to give it a good cleaning, and to see what it looked like inside. The guy that did my pool startup was a joke, and I wanted to inspect it. I never back-washed since the installation, btw. So, here is the question: Should I see non-DE junk stuck to the grids, or is this a clear indication that not enough DE was added?
My understanding is that, when properly done, the DE should coat the grids, and the junk should really never contact the grids. Am I missing something? Is is safe to assume that my start-up pool guy screwed this up (along with just about everything else)?
Thanks,
