My floater rod is a 1.75lb Specialist rod, which swaps between roach, bream, tench and chub as well as carp.
Years ago I bought a Shimano aero 4000 gtm fighting drag with spare spool, but one of the current 4/5000 size baitrunner reels should be perfect.
Obviously match your line to the lake, some places 8lb is fine, others it is 10-15lb plus. The 8lb I use for feeder fishing for the 'little' species as well, including floater fishing for chub.
Hooklink wise I tend to water knot an arms width of hooklink, Berkeley Trilene xl below 10lb, Preston Reflo above 10lb, usually to a size 10. Hooks, Drennan Super Specialist, Solar 101's work for me.
As for dog biscuits, a box of Bakers Complete gives a mix of shapes and sizes and a very nice hook bait with the big square ones.
If close enough freeline, if further out a decent controller, and wait for it, but a Nash Tackle recommendation (I feel faint and ill saying that, 😆) the Bolt Machine.
