So I've been reading about tank set-ups and what type of sand bed, if any, should be used for optimal filtration. Right now I have a SSB and I think I might have gone wrong. What I read was that a sand bed doesn't help you unless you have water flow through it, in fact it might hurt you. The only way to get your sand bed to work for you is if you set-up a plenum type system where the sand bed is not actually in contact with the botom of your tank. This is what allows your sand to "breath" and actually act more like LR. Looking at the poll I would have to believe that this is not the norm. I'm guessing that if you can create enough water flow over your sand and not let detritus build you're ok. Can anyone help explain or maybe easy my mind?
