Need sump advice, pro flex model 1

[Double J]

So I had an outbreak of ich and will be moving all fish to a hospital tank tomorrow. So what better time to upgrade the display. I'm looking at the proflex model 1 sump by aquaeon. Mainly due to size restrictions unless I modify my stand.
I'm wondering if anyone has used one of these? I hope to have a refugium for macroalgae as I have been battling green hair for about a month now. My concern is with the small size how I can have the refugium and also move my skimmer and heater to the sump.
I would love to see pics if anyone uses this sump and also recommendations for a smaller but efficient skimmer. Looking at either the aquamaxx ws-1 or tunze 9004.
Also could use recommendations for overflow box, looking at the eshoppps eclipse, but see issues with water height being low.
Thanks

has anyone used a hob skimmer on a sump? seeing that most in sump skimmers are too big for this sump and thought I could maybe use my aquamaxx hob-1 on it?
