Gman and Richard are right. After you messed with the sandbed did you notice a "rotten egg" smell? If not, that is good as hydrogen sulfide is extremely toxic to your tank (high doses are bad for us as well). If you did smell you need to do major water changes, test a lot and run carbon. If not then you are on the right track with water changes.
