2 primes and 2 pumps. I have a Nero 3 and it's a good choice. I also have a Jebao 'gyre' but I couldn't get a minimum flow that was gentle enough for my LPS and pulled it out, however I have no personal experience with the 4k/2k and that may work just as well.

As things grow in you will need to adjust things anyway, but 2 Nero 3's will take you a long way on a 3 foot tank IMO.
