Deep sand beds

[reefburnaby]

Hi,

Sand should be fine as long as it is silicate sand. Unfortunately, it is hard to tell if you have silicate sand if you are at a beach. The risk is that you'll have some sand that will leach heavy metals or other minerals back in to the water. Sand blasting sand is a bit different since it is , more or less, very pure silicate sand. Grain size should be okay...just compare it to domolite lime. If the grain size is about the same...then it should be fine.
