Skimmer for Elos 70 build

[ReefMonkey13]

HI All,
I'm planning a build for an Elos 70 (55 Gallon) I will have either a 20 or 30 Gallon sump.

I was considering the Aquamaxx Cone S CO-1 but they seem to be hard to find. Can anyone suggest a good skimmer for a 50-80Gallon tank.

Thanks in advance for the guidance

I'm running a Bubble Magus NAC-7 on mine and it works great.
