can any one tell me if its ok to stir the sand bed when you do a water change. they say not to vacum the bed but just did not know if you can stir it.:notsure:
Yes it is fine to do this to improve the circulation within your sand bed. However, it is probably best to do this when you are not doing a water change so that you don't lose a lot of the smaller particles.
That strange!!!! I thought every time you did a water change, u
should always shovel the sand bed or crush coral to remove any
debris from it.....Please correct me if i'm wrong.....
If you only siphon the top, it should decrease your nitrate reading because you've siphoned away all of the stuff that'll break down and turn into nitrates.
