Iv never had or looked at the aqueous kits, but I would say the lights will be worthless if your wanting corals. Also, based on what iv seen with nitrate in my saltwater aquarium compared to my freshwater, which contains canister filtration, I would never consider a reef aquarium without a sump. Mine does have a sump, good protein skimmer, and a refugium full of macroalgae and I'm still around 10 ppm
. Still a young tank and things need established but I couldn't imagine what they would be if I didn't have the sump that I do.
Give more specs on this kit and I'm sure they are many in this forum that can help ya out.
