I posted about the cadlights over at reef central as well. Unless that 283l/h of air is a mistake there is NO way it will skim a 90g tank let alone a 55g heavy stocked tank effectively.
I would have gone with a Bubble Magus or SRO skimmer for your application, but keep us posted on the performance of the CadLights, I know their build quality is excellent!
Got the new skimmer yesterday. Just hooked it up and running. I am keeping my old skimmer in the sump along with it. Cleaned the old skimmer and going to see which will pull more stuff out.
