Cleaning of the Jar and Substrate

The day that i received the jar and substrate I got to work immediately. I first rinsed out the jar for quite a number of times just to make sure that there was  not any toxic chemicals on the inside of the jar that could harm or effect the bahaviour of my fish.

I then put my substrate in the jar, filled it with water and gave it a nice shake. I then waited for 5-10 minutes so that the subtrate could sink to the bottom of the jar and then all material floating on top of the water I would get rid of by throwing the "dirty"water out. I followed this procedure for 7 to 8 times to make sure that there was nothing left in the substrate that could harm DJ (my fish).
