Alright I will try to answer all these questions.

-I don't think overfeeding is an issue as I only give them what they eat a couple times a day.
-I am doing water changes everywhere from 1 week to 2 weeks and sometimes more often as I am trying to get the nitrates down.
-My salt tests at 1.024 using a refractometer.
-Not sure about dissolved solids in my water as I get it from a business who's line of work is purified water who's rep is well maintained with fish keepers.
-Inside my filter is bio foam, foam, biomax and carbon.
-For water changes I do between 20-40%. I have increased recently as I am trying to force water levels to go down.
-My live rock came from a supplier that my work deals with based in Vancouver. It was per-cultured.
-I use nutrafin for my test kits.

Any help and criticism are appreciated as I need all the help I can get.
