you could try increasing the sizes or frequency of your water changes and cutting back on the dosing. Your Alk (KH) is quite high and your Cal is quite high depending on your corals. If your coral load is quite small you may not need to supliment at all. Most people dont worry too much about thier pH and dont tend to try to change it too much. The tank will usually find its own happy medium. It appears that you may be over feeding a little if there is that much left over food and it appears you are running some kind of mechanical filter and no skimmer? thus would be the source of your nitrates. 4-6 weeks is way too long to leave a mechanical filter running without changing it.
