DSB for freshwater

It will probably colonize more bacteria but it will also be a place for wastes and food to decay. So i dotn think it would have the same effect.
 
Why would the food not waste and decay there in saltwater?

I have never kept sw so I am not really familiar with it. I was just reading about dsb.
 
saltwater tanks have more invertebrates that stir up and help clean the DSBs. crabs, starfish, worms, seacucumbers etc

Also with sand packing so tight it is an opportunity for anerobic bacteria to breed and release gas that might destroy your FW tank. Wait a tick, I'll see if I can drag up that thread.
 
I was going to say the same think as matak but i forgot what hte bubbles were called. And in a SW aquarium, the creatures in the DSB eat the wastes. Also waht hebdizzle said.
 
Can't seem to find that thread about the disasterous gas percolating in one members tank. The gas given off really dropped the pH and killed the entire tank. Any clues?
 
I remember one thread about a lady that has kept fish for like 15 years. She was doing a water change and 3 little bubble came out of the sand and then 10 seconds later all of her fish were dead.
