well thats all fine and dandy that RHF's tank can handle the extra nutrients.....many people's tanks cant handle the extra nutrients.. either due to bioload or perhaps other supplementary feeding, such as corals or nems etc....and I would venture to guess the the OP's 7g skimmerless(Im assuming) tank might fall into the category of less nutrients is better
