A bit off topic, but related...

Is there any special procedure to cleaning the sand as compared to gravel? Do you lose a whole lot of sand using a gravel Vac?

I would assume similar for using a substrate for plants? Go into the gravel almost to the depth of the substrate?

Does that get to be a pain?

Also (hopefully not going too far off topic), can you add substrate to a tank that already has gravel in it? How?
