For Thornbreaker: in a new tank, there isn't that much to pull---yet. If you've got colored water, it's working; unless it's on an old tank---then it's not working enough. Mine is near black, older tank. But yes, you just keep adjusting the flow until it produces color.

For RDNVA, a type that uses a rubberized flexible impeller tends to produce the good foam. My own is an E-shopps, a model rated for a 200 gallon, but I use it on a 100. In all but the highest-end (spendiest) skimmers, going for a model advertised to handle twice your tank volume is a good match.
