There could be lots of beneficial critters added to tank that he normally wouldn't have. Do the risks out weigh the rewards?
Its not bacteria die off that would cause the spike.... Sand is full of rotting poop, leftover food, etc. It has been said a million times on the forums do not stir up your sand bed because because you are releasing all of this into the tank. This is why when you move a tank you should start with fresh sand. You have the benefitial critters in your tank already. The tank your getting sand from was started the same way yours was. Its just not a good idea. The risks far outweigh the rewards and I just don't see the point, you wont be adding anything that you dont already have.
