I have never owned a pool before. I purchased an above ground pool online and it came with a Clearwater 2 D.E. filter. I followed all the instructions to set it up. After watching some YouTube videos, I noticed other people where adding D.E. powder to their systems. I have been pouring over the info that came with the system and it doesn’t say anywhere about adding powder, but it did come with a measuring cup for for D.E. powder. I need help to figure this out. Thank you!
