What type of flatworm is this?

[krak256]

Found these in my sump; I don't believe they are AEFW or planaria but would like some help. I dosed flatworm exit and it didn't appear to affect them:

Acoel flatworms

Red ones are usually planaria. Clear or white usually good hitchhiker.

The acoel flatworm, commonly known as "Rust-Brown Flatworm" is a photosynthetic flatworm that can reach plague proportions. This is the main reason they are undesirable, looking unsightly and smothering low flow, light intense areas throughout the aquarium. The rust brown flatworm is a non predatary, photosynthetic flatworm, and as such, does not directly impact the inhabitants of the aquarium. Best removal method is to siphon them up with either a 3/8" or 1/4" tube.
If there are too many, several wrasses will eat them. Wrasses: Yellow coris, canary, 6 lined, lunare and melanurus

Last option is salifert flatworm exit . Be sure to again siphon the dead ones which can release toxins. Look daily for 14 days for presence of eggs which are tiny and scrape them off outside the tank

thanks everyone. I actually used flatworm exit last week and still see them. I believe I actually dosed at 3-4x and still see these flatworms moving about in the sump

Increase the strength by 20-25%. Siphoning them up is most effective.
