Maybe you missed the point ? ... the idea was that a substrate was used ( as opposed to NO substrate Ie. barebottom ) but without the maintenance of either a barebottom tank or even a shallow sandbed ... nothing to do with sand critters ... make more sense now ? ... actually I will take it one step more ... if you have a shallow sand bed you will have to vacuum it for detritus ... dont you think you will be vacuuming up those sand critters too ?
