Over the past few months my nitrate level has started to climb more than I would like (around 5ppm I believe using a Salifert test kit). I have a sand bed that is probably 2-3" deep. When I originally started the tank I used a combination of live marine sand, aragonite, and crushed coral. The crushed coral was probably a mistake. It looked great at first, but has probably added to a series of challenges. I am going to have to redo some of my rockwork anyway. Is there any advantage/disadvantage to stripping off the top 1/2" or so of crushed coral? I do not want to cause a nitrate spike, but I also do not want the nitrates to continue to climb over time.
