I haven't used sand yet in any of my tanks but wanted to put some in with my crayfish.The marine/freshwater type of sand I got says you just presoak it.But a lot of gunk came to the surface.And I'm not sure if I can add the sand to a tank with water in it or if I need to drain and refill.I am going to use a terra cotta pot in the tank and was hoping I could just fill it and then situate the pot in the tank on it's side with the sand spilling out of it.But I am not sure if it will cloud the water.
Any input would be appreciated....thanks.
