If you don't clean your sand properly, there is a risk that the water could be cloudy. If you rinse and clean your sand, it will never be an issue. All of my tanks have sand, take a look at "My Tanks".
I've used Play Sand, Beach Sand and lately Quikcrete All Purpose Sand. The Play Sand takes too long to clean, the Quikcrete being the choice I would use again.freddy1477 said:thanks man nice tanks what kind of sand do you use?
