Moose I don't know if this much light would work with the EI, or any water column fert regime-without resulting in algae soup, For me I get away with high light, but my strategy is to have lots of plants, and keep the water column fairly sterile and keep the nutrients in the substrate. Now this may rule out some plant species all together, especially if CO2 is not used. I think being conservative with bioload and photoperiod are also important when playing with fire to keep the right balance.
Consider it a diffrent strategy perhaps. It could go horribly wrong if you are not careful, but it can be done and there are lots of examples on here, even sans CO2.
