The second one is the 40b.
If you are absolutely going with no sump then a large hang on filter like an aquaclear is a good choice. Big enough to run what you may want to run when you need to, like gfo
, for phosphates or carbon to clear up the water. Live rock is your primary biological filtration so the filter is just for particulate matter and to run chemicals when needed.
As far as skimmer, I would suggest a small hang on back version, like an aquaC remora or maybe an eshopps. Lights will be dictated on if you want corals or not. Expect to pay over $100 for a skimmer and over $100 for a light, but under $200.
