Are you cleaning the subatrate, lifting all the decor & cleaning under it? There has to be some uneaten foods rotting somewhere in your tank. I'd up that to at least 50% weekly. I do 75% on all my FW tanks & 90% for my discus.
to keep my nitrates down I do a 120% w/c weekly, just to give you an idea, every 3-4 days I have to change out 60%...keeping your nitrates down is like a math equation, if yours are at 40% and you change half of your water, the new number will be 20. So your residual nitrates are going to kick your butt only doing 15% waterchanges, IMO you would really be better off to do less frequent, larger water changes (ie 50-75% a twice a week) than 15% a day with the fish you have.
