I don't like skimmers in my set ups. But I have never had anything over 40g. I have chetao in a refugium hang on I put together with super glue and a cheap but decent grow light, with a timer. Both amazon specials. The hang on breeder is supplied by an air pump so there's not a pump to chop up the pods. I currently keep a bag of chemipure blue in the sump. I use filter floss in my return and change that when it looks rough. I feed daily and change 2g weekly; 1g 2x a week. And I dose small amounts of sodium nitrate to balance out the phosphates for macro consumption. It depends but if I added a skimmer with my macros, my corals and anemones would get stressed and be hungry most likely. So my 2 cents is chose between macroalgae in a reactor/refugium or a skimmer.
