You should not skimp on food no matter what the reason. Instead you can incerase the frequency of your water changes drastically. You can do 50% or more if you pre-heat the water. Also, look for places that detritus and uneaten food may be collecting. You can increase flow in the main display to keep food suspended until it is eaten or filtered. On that note, you should also increase the frequency of mechanical filter media changes if you have not already. You might also look into the quality of the water you're using as makeup and top off. Do a PO4 test on the fresh water you use before you mix your salt. It should read zero or close to it.
