Substrate question

[Chin_Lee]

if you are contemplating on BB or substrate, go BB first. If you still don't like it after a few months, then add substrate. Otherwise its a PITA to do it the other way around.
I concur with the BB supporters - crud is inevitable and I feel that sand just hides it really well. some critters in your live sand will eat some of the crud but you will never have enough critters to sustain an aquarium environment's bio-load.
I can relate to this theory by this scenario - imagine yourself and your entire family being stuck in your house without any methods in which to remove your biological waste but a mysterious hand will continuously put food and water into your house to keep you alive. You are real happy for the most part because there's the big screen TV, computer, workout gym, various boardgames etc. However everyone dreads having to go to the bathroom but when they do, how many critters will be needed to live with you in your house to continuously eat and remove all that biological waste in your house? HOWEVER if that same mysterious hand can come in with a plastic tube and suck out all that biological waste, I think it will be somewhat ........ alright.
