I opened my pool a couple of days ago. It usually takes a week to make the pool clear/clean with a lot of shock. I also backwash about 2-3 per times day for the first week. After I backwash, prime and start the filter again, a little bit of DE goes back into the pool from my booster pump/cleaner line and my spa lines.

Is this due to too much DE, not enough DE or something else?

When I backwash, I only do it until the dirty water disappears and clean water appears. I do not wait until the entire filter is empty. Could this contribute the the DE returning to the pool?

You may have something wrong with your DE filter. You shouldn't see any DE going back into your pool.

Could be a tear. You may be able to get replacement parts for it but if it's really old and needs extensive parts, you may want to buy a new one which would have a good warranty.

With a DE filter, you should backwash until clear, shut pump off, close bw valve and run normal for a few seconds, then bw again a couple of times.
Then recharge your DE through your skimmer.
