Mine is a sand filter, can't hep with the DE disposal.
I backwash onto my lawn, have done for 7 years, no problems. My FC generally is between 3 - 5 ppm and has not hurt the grass.

My observation with the lawn is that the pool water with ~3000 ppm salt only makes the grass greener. I normally only backwash every 2 weeks or so, or maybe longer. I have had troubles the past few years so I have backwashed more often. Sometimes I only bw once a month.

Find the sewer clean out in front of your house and back wash into that . If you're not on septic that is.

My backwash goes into my back yard, usually with5-10 ppm of chlorine, and it doesn't hurt the grass at all. As far as DE goes, some folks actually spread it onto their lawns to help control insects.
