So what is the verdict on preparing/cleaning rock to put in the tank. Thinking of using some river rock that's been lying around in the yard.
Do you boil the rock for a few min. do you just rinse it in water? do you add anything to the water while soaking the rock, (maybe a little bleach) or do nothing?
thanks
