I have been searching for sand to put in my tank, and I think I am more confused than when I started. I have been told not to use play sand from Home Depot, Lowes, etc. because it is too fine and will stay suspended. Then I am told to use pool filter sand, so I took a trip to two different pool and spa places and they both only had clear sand made from recycled glass which was $25 for 50lbs. One of the guys at a spa place told me that I was probably looking for 20 grit silica sand, and that no pool or spa place carries that anymore. Where do I get this elusive sand without spend a rediculous amount for aquarium sand?
Also, how much do I need for a foot print of 96"x30" that will be thick enough for plants?
