PoolSkim circulation

Hey gang. Nice to find this place. I have a question about using the PoolSkim that I just bought.

How do folks fine tune their returns to encourage optimal water circulation generally, as well as to take advantage of the PoolSkim product? I seem to have dead spots in a couple places, even after trying to point my eyeballs.

(16x32 rectangular IGP, 2 skimmers & main drain, 2 returns on long sides opposite skimmers, plus a dedicated return/outlet for the Polaris pool vacuum).

Thanks for any suggestions.

I think some people use this directional return eyeball for that purpose:
