I have a 55 gal tank that has a deep sandbed maybe 3-4 inches. I think this was affecting my nitrates as they were at about 100. Water changes and removing some of the sand a bit a time has gotten me down to 31. Currently in removing a little sand with my weekly water changes. I’m worried I may release gasses that will nuke my tank. Will I be okay only removing a little once a week or do you think I will eventually hit the deeper part of the sand and nuke it by releasing gasses. Removing the fish to do this isn’t an option.
