I f you have success with planted aquariums ,why dont you try the algae scrubber for filtration system? With marine aquariums there is a problem with the surface film ,youl have to fix that and theres no need for a skimmer in case you go with algae scrubber.Light is verry important and i would reccomend T5HOs each with individual reflector.14000K-16000K.Add litle sand because it gets clogged over time with detritus.As far as corals go you could grow a lot of LPS like caulastrea and soft corals in such an aquarium and somme of the hardyest sps species too like birds nest coral(the green one,the pink one cant resist much if the water gets hotter),stilopora.For chilling the water you could use fans directed to the water surface or a chiller would be the best approach.
